How long do brake hoses last?
Data updated
Quick answer
Across every car tested in Britain, brake hoses fail the MOT at 0.0 per 100 tests at three to five years old and 0.7 at 15 years and older — 67 times the rate. Failures reach half their peak from 15 years, which is when to have them checked. Flexible hoses perish, crack and chafe with age; a bulge under pressure or exposed reinforcement fails.

Common questions
- How long do brake hoses last?
- Across the British fleet, brake hoses barely fail before 15 years and older: 0.0 failures per 100 tests at three to five years, rising to 0.7 at 15 years and older, 67 times the rate. Flexible hoses perish, crack and chafe with age; a bulge under pressure or exposed reinforcement fails.
- At what age should I have brake hoses checked?
- From about 15 years, when failures reach half their peak rate across the fleet. Advisories for brake hoses run ahead of failures by a year or two, so a car whose MOT history shows one is on the curve.
- Is a worn brake hose an MOT failure?
- It depends on how worn. "Brake hose deteriorated, damaged or chafing" is the defect testers record; each page explains the threshold at which the item fails rather than being advised.
