The link will include the invoice number and the total amount payable (including delivery costs). You may be asked to follow some security steps via your bank before the payment is cleared or whilst completing the payment, this is standard and something between you and your banking provider. If you need a refund or part refund and you paid using the pay by link then it is simple and a refund can be issues easily. You will get a confirmation email from World Pay when this has been done.
  • Can I order goods to be paid for on delivery?
    Unfortunately not, COD (cash on delivery) services have been withdrawn for both inland & international despatches.
  • Will I have to pay any duties or taxes on importation into my own country?
    For those customers outside of the UK there are import duties/ custom charges that you will need to pay, typically you will be notified by the carrier (ie DHL. FedEx, Royal mail etc) that you will need to pay the import duties/custom charges on these goods. It is the responsibility of the customer to pay the import charges on purchases as they are the “importer”.
  • Can I pay in US$?
    All AlfaStop business is conducted in GBP, & all offers & invoices are in GBP although an indication of the approximate US$ cost can be given. You can also get the website to display prices in local currency by selecting it from the drop down menu. However, a payment on, for example, a US$ based credit card, will be converted into US$ by the credit card company before billing to your account.
  • How are orders shipped?
    We are able to ship across the world, we use Fed Ex, DHL and Royal mail. Although we cannot give exact shipping costs on the website, we work with our courier services to get the best rate possible. We are happy to get shipping quotes prior to proceeding with order and offer the customer to choose the best option for their needs. Please refer to our Shipping Policy.
  • Can I have my order shipped to a different destination or person?
    Yes, all we ask is that you make sure you have the correct address and contact details we will do this.
  • Can I add to my order or do I need to add another order request?
    Please just send us an email, message or call with any additions. It's not a problem to add or amend orders before they are sent out for delivery.
  • How can I be sure that the part which I am ordering is the part which I need?
    Many items which appear on our website listings have a photograph to help you confirm that the part is what you need. You will also find information on the quantity of a particular item which are used on one car. You can further check by referring to a copy of the Parts Book to confirm the identity, we quote the original part number wherever possible to help you. You can also telephone or email us to discuss your particular query - we are always happy to discuss what you need and help with solutions.
  • What does "Quantity Per Car" mean?
    "Quantity Per Car" gives you an indication of how many of the item are required per car, & how many should be bought if all items are to be replaced. Thus: (1) indicates that one of this item is required per car (2) indicates that two of this item is required per car (16) indicates that sixteen of this item is required per car. Note that: The quantity refers to the application under the specific listing, so, for example, if (4) is shown as the number of brake drum retaining screws on the front brakes listing, more may be required for the rear brakes - which will be shown under the rear brake listing. In general, brake repair kit & fitting kits contain sufficient parts for 1x axle, so a quantity/car of (1) will be shown. Most parts can be supplied in quantities less than the quantity required per car.

  • What parts does AlfaStop actually stock?
    AlfaStop probably have over 95% of all the items listed in stock & ready for despatch. This includes large items such as fuel tanks, windscreens & exhaust systems. AlfaStop does not list a wide range of parts & then buy them to meet a particular order.
  • What is an "exchange" item?
    An exchange item is one where the customers sends an old unit. This is then either actually rebuilt & returned to the customer, or is exchanged for another unit which has already been rebuilt.
  • Can you send windscreens internationally?
    We are happy to ship glass screens. These will be sent in purpose built wooden heat treated crates, we are happy to ship internationally but the glass does have to go in the purpose built creates and where we can will try to obtain the best shipping rate we can.

  • Why is it called AlfaStop?
    Well, back in 1992, Tony Stevens (original owner of AlfaStop) started by selling brake parts for Alfa Romeos. Brakes make Alfa Romeos stop, hence "AlfaStop"!
  • Who manufactures AlfaStop parts?
    Products are sourced from first-tier suppliers such as Lucas, Girling, ATE, Ferodo, Pirelli, Bosch and Fichel & Sachs who were original equipment suppliers to Alfa Romeo. They are also sourced some parts from second-tier suppliers who supply individual components to first-tier suppliers such as those mentioned above. AlfaStop has also commissioned the manufacture of parts from companies which supply components or assemblies to companies including Aston Martin, Lotus, McLaren, Rolls-Royce & VW-MAN AlfaStop rebuilt components are sourced from companies whose customers include Aston Martin, Ford, Rolls-Royce & several Formula One teams.
  • Are AlfaStop parts cheap?
    AlfaStop doesn't sell cheap parts. But we do believe that we sell parts which are of good quality & at fair prices. We are always pleased to give you the current price and availability of any parts which you require, together with the most economic delivery cost.

  • Should I just change the seals in my brake cylinder or replace the whole cylinder?
    Brake repair kits were originally offered as a temporary or "get you home" service part to be used for a relatively short period. However, over the years they came to be used as a permanent repair solution. With many original hydraulic items now being up to 50 years old, it is essential that the condition of the cylinder is thoroughly examined before making a decision whether to reseal or replace the cylinder. We regularly hear tales from owners who have replaced brake seals together with relining the shoes, only to find within a short time that a leaking cylinder has contaminated the brake linings.
  • What is so special about the AlfaStop brake lining material offered for Giuliettas?
    We believe that FERODO MZ41 to be the finest lining material for classic Alfa Romeos. It was specified by Alfa Romeo for original fitment to all production models from the 1900 Berlina of 1950 through the Giulietta, 2000, 2600, to the first Giulia 105 series TI models which were fitted with front & rear drum brakes. My opinion is echoed by most UK historic Alfa race & rally entrants who love it. MZ41 is a woven asbestos based material incorporating zinc wire (hence the Z in MZ) with a high fade resistance making it suitable for arduous competition use as well as day to day normal use. I was fortunate in being able to purchase the entire stock of MZ41 from FERODO before it was discontinued. As stocks of MZ41 are now diminishing, we can now offer asbestos-free MZ. We offer lining sets containing pre-drilled linings & rivets for fitting by Customers, together with a relining service of Customer's own brake shoes.
  • Are braided stainless steel brake hose road legal?
    Standard braided stainless steel brakes hose have the end fittings assembled onto the hose by means of threaded components. These hoses are theoretically not road legal because the various national approval bodies require that the metallic end fittings are crimped onto the hose. AlfaStop's TUV approved stainless hoses were the first to be manufactured with specially developed crimped end fittings which have been tested & approved by one of the several German TUV test houses. Each hose is so identified & is supplied with a copy test certificate. TUV certification is accepted in the USA as being equivalent to US DOT approval. DOT stands for the US Department of Transportation which publishes standards for many types of motor components. DOT3 refers to a set of brake fluid specifications, a supplier might claim that a fluid meets, or exceeds, the requirements of DOT3.
  • How regularly should I change my brake fluid, & why?
    Manufacturers of both fluids & cars seem to advise changing brake fluid every 2 years or so. Most brake fluids are hydroscopic & absorb moisture over a period of time. The fluid's boiling point is then reduced, with possible serious results under hard braking.
  • How can I tell if I have Dunlop or ATE brakes on my Giulia?
    Dunlop front calipers have a single pad retaining pin in each caliper, & the rear calipers are mechanically operated by a cylinder mounted on the rear axle tubes. ATE calipers have two pad retaining pins in each caliper, front & rear.
  • Why does AlfaStop have its own range of brake cylinders?
    With some of our cars approaching 50 years old, it is becoming difficult to obtain some items from the original suppliers. This situation is magnified by the increasing desire of companies to sell large quantities of an item in order to justify keeping it in their product range. Clearly, 2600 rear wheel cylinders do not sell in the similar quantities as those for a VW Polo. AlfaStop has commissioned the production in the UK of a number of new cylinders for 1900, 2000, 2600, Giulietta, Giulia 101 & Giulia 105 Dunlop braked cars. These cylinders are fully interchangeable with the originals and can be installed either singly or as a set. AlfaStop does not stock any unbranded hydraulic parts of unknown origin.
  • Are rebuilt units suitable replacements for the original units?
    Most commercial & military organisations use rebuilt components, be they printers, guns, gearboxes, you name it. AlfaStop rebuilt components are sourced from some companies whose customers include Rolls-Royce, Aston Martin, Ford & several Formula One teams.
  • I hear about arcing brake linings. What is it?
    Arcing a brake lining is a workshop operation which closely matches a lining which is installed on a brake shoe to the dimensions of the brake drum. This operation is particularly popular in the USA, less so in Europe where the machines are rarely found.
  • My brake linings have been contaminated, what can I do?
    In general there is little that can be done since the materials usually contain cotton which acts as a wick & absorbs the contaminating fluid.
  • What is a re-sleeved cylinder?
    A hydraulic brake or clutch cylinder which has a pitted or scored internal bore can be reclaimed by drilling out the bore & inserting a sleeve to return the bore diameter & condition to that of the new original cylinder. This is a specialist operation & is usually only cost effective when a new cylinder is either no longer available or cannot be obtained in the required time-scale. Re-sleeving is particularly popular in the US & Australia. The success of the sleeving operation is dependant on the skill of the operator in ensuring that the sleeve is secure in the cylinder, is leakproof, & is of sufficiently high surface finish.
  • What is the benefit of a stainless steel brake caliper piston?
    The main benefit is that it can be easily produced in low quantity (even a single piston) & can be ready to fit, requiring no further finishing or chroming. The unknown factor is if the dimensions of the new piston take account of the different thermal expansion properties of stainless steel. AlfaStop does not usually stock any stainless steel brake caliper or cylinder pistons.
  • What is the difference between a normal steel exhaust & a stainless steel exhaust?
    AlfaStop's normal steel exhaust systems are now made from aluminized steel which is treated so as to reduce the liability of corrosion. Recent reports received seem to support this. The silencer boxes are double skinned, as the originals, & most tailpipes are chromed. Considering the low production volumes of these systems, we believe that they are good value. There are stainless systems & stainless steel systems, just as there are stainless steels, & less stainless steels. Our range of stainless steel exhausts is hand-made exclusively for Alfa Stop in the UK by a long established manufacturer. Notable features include 304 grade austenitic stainless steel throughout, 1.2mm thick for silencers boxes, 1.5mm thick for front pipes & 1.2 mm thick for other pipes. Note that some suppliers use the cheaper, less corrosion resistant 409 grade for silencer boxes &/or pipes, this inferior material is also more prone to fracturing. All flanges on AlfaStop stainless systems are laser-cut from stainless steel plate, silencer boxes are packed with high grade E-glass wool, tailpipes are highly polished, the system is designed for correct alignment with original mountings & accepts original gaskets.
