Brake hose chafing and corrosion of the hydraulic lines
SeriousBrakesThe P11 was caught by DVSA recall R/1995/063 (and its follow-up campaigns on the platform) for front flexible brake hoses that could chafe against surrounding suspension components and split, losing hydraulic pressure. On surviving cars the rigid steel brake lines running over the fuel tank to the rear multi-link beam are also a classic MOT failure point in the UK: winter salt and road spray lodge above the tank, rotting the lines unseen until the pedal turns spongy or drops under heavy braking.

- Press the brake pedal down firmly with the engine idling and hold for 30 seconds to confirm no pressure loss
- Inspect the front rubber flexible brake hoses at full lock for chafing marks, cracking, or bulging
- Shine a torch over the rear subframe and fuel tank to check the steel hydraulic brake lines for crusty rust scale
