Frequently asked
How do I know a part will fit my car?
Enter your registration above and we cross-check against the TecDoc catalogue to narrow the list to brake master cylinders listed against your vehicle. Specifications can still vary between trim levels and engine variants, so we recommend confirming the part dimensions against your existing component before fitting.
What brands do you stock?
We stock established manufacturer brands sourced through trade channels. The brand row at the bottom of this page shows which manufacturers we carry for brake master cylinders. We don't sell unbranded parts.
How quickly will my order arrive?
Most orders dispatch from our Northampton warehouse within 1–2 working days. Free standard delivery on orders over £40 to most UK mainland locations.
What if the part doesn't fit?
Please check our returns policy for the current terms. If you're unsure about fitment for your specific vehicle variant, please contact our team before ordering using the details at the bottom of the site.
Can I check fitment before ordering?
Yes — every product page shows whether the part is listed against your selected vehicle. Where multiple sizes exist for the same vehicle, the dimensions are shown so you can compare against your existing part. If you're unsure, contact our team for help confirming the right option.

About Brake Master Cylinders
Our brake master cylinders range is built from established UK suppliers and trusted aftermarket brands. Each product is mapped against OE/OEM references and TecDoc ktype data so the reg-lookup above filters to only the parts that fit your specific make, model, engine and trim.
Enter your registration to see exact-fit options — or browse by brand using the tiles above. The full catalogue covers most major makes and models on UK roads, with same-business-day dispatch on stock items ordered before 2pm.
When to replace your brake parts
Brake pads and discs are wear items — most workshops check pad thickness at every service and replace them before they hit the manufacturer's minimum spec. Discs typically last 2-3 sets of pads depending on driving style and dust composition. If you've noticed any of the signs below, it's worth ordering a fresh set before they fail.
Common signs your brakes need attention
- High-pitched squealing when braking gently — the wear indicator has reached the disc.
- Grinding or scraping — pads are below minimum, metal-on-disc contact.
- Longer stopping distances or soft pedal — pads, fluid or a calliper issue.
- Vibration through the pedal under braking — warped or unevenly worn discs.
- Pulling to one side — uneven pad wear, a stuck calliper, or a fluid contamination issue.
Choosing the right parts
Specifications vary between trim levels and engine variants — a 1.6 TDI saloon may use a different brake set to a 2.0 TFSI hatchback of the same model. Confirm part dimensions against your existing component before fitting; our reg-lookup checks OE references but the diameter and pad shape are the final verification.
