About Car Brakes - Brake Hydraulics
Our car brakes - brake hydraulics 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.

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.
