Soted the problem. I had put too much Brake fulid in the container, so i soaked some up and it doesn't lock now, even at high speed. | |

yeah, i will do that. it may be jammed. Hopefully i won't need to renew the brakes | |

when i had my MOT they were fine as they pulled the handbrake up and tit locked so they said it was fine. I will have a look at the bias valve. What shall i do with the valve and how much are new brake shoes for the rear? | |

the bias valve is on the rear beam, on the drivers side, look under ull see it. but ithink itll be the rear brakes, when were they last replaced? | |

when the rear brakes need replacing the tend to lock up first, seen it before, check the bias spring if you like, its on the rear beam on the passenger side, if the cars not lowered tho cant see that being a problem | |

could be as when i replaced the front brakes the pdeal went straight to the floor due to sticking pads, so the rear shoes lay have over componsated. | |

It sounds like the Bias valve is jammed and the car thinks that there alot of weight in the back when theres not hence more brake pressure to the rear | |

onyl other thing i could suggest is rest the auto adjuster so the shoes anrt as close to the drum | |

why's that. If they needed replacing, this would be becuase they don't lock or brake at all. My hand brake works fine and the brakes just lock up when i apply quite abit of pressure on the pedal. | |

Any idea why my rear drum brakes are locking up when i brake heavily at low speed? I recently changed the front disks and pads and topped the brake fluid up |
