Brake Hose Buying Guide
Last updated: 24 April 2026
Brake hoses are flexible hydraulic lines connecting the rigid brake pipes to the caliper or wheel cylinder. They flex as the suspension moves and the steering turns. Over time they deteriorate internally, restricting fluid flow or ballooning under pressure. At CarParts247 we stock brake hoses from ATE, TRW, and Ferodo.
When to replace brake hoses
Rubber brake hoses degrade from the inside out, so external appearance can be misleading. Internal deterioration acts like a one-way valve, causing the brake to bind or pull to one side.
- Cracking, bulging, or chafing visible on the hose outer surface
- Brake pulling to one side — a swollen hose restricts fluid return
- Spongy brake pedal that does not improve after bleeding
- Brake binding or overheating on one corner after release
- Any fluid leak at the hose-to-caliper or hose-to-pipe fitting
Fitting and bleeding
Brake hose replacement requires bleeding the hydraulic circuit to remove air. Use the correct brake fluid specification and never reuse old fluid.
- Use the correct fitting spanner — do not round the flare nuts
- Replace copper sealing washers on banjo fittings — they are single-use
- Bleed the circuit after fitting — start from the wheel furthest from the master cylinder
- Check hose routing to avoid contact with suspension components through full travel
- Use the manufacturer-specified brake fluid (DOT 4, DOT 5.1, etc.)

Frequently Asked Questions
How often should brake hoses be replaced?
There is no fixed interval, but most manufacturers recommend inspection every service and replacement every 6–10 years or if any deterioration is found.
Can a bad brake hose cause pulling?
Yes. An internally collapsed hose restricts fluid return, keeping the brake partially applied on that wheel. This causes pulling, uneven pad wear, and brake overheating.
Should I replace all brake hoses at once?
If one hose has failed due to age, the others are likely in similar condition. Replacing all four at once is good preventive maintenance.
What is a braided brake hose?
A braided stainless steel hose replaces the rubber outer layer with a metal braid. It resists expansion under pressure better than rubber, giving a firmer pedal feel. Popular as an upgrade for performance driving.
