    Hi I needing help urgently... so I had to change my rear offside caliper on my disco 2 td5 2000. After installing, me and my partner have tried to bled the breaks for over an hour (she is pumping brakes and holding whilst i am doing the bleed valve). Problem is that my brake pedal is staying hard to push (gets easy when releasing valves but goes hard as soon as valve gets tightened up) when realising the valve the brake fluid is coming out with no bubbles (which i thought meant there is no air in system?!)... do any of you know what maybe the problem? Should i trying bleeding the whole system? (Starting from furthest point from master cylinder and doing all four wheels). Tia

    If the pedal goes hard, that usually means there is no air in the system.

    What exactly do you mean by being hard to press? Do you mean you need more force than usual to push the pedal down, or that it goes hard when the free pedal travel has been taken up. Are you doing it with engine running? What are the brakes like when the vehicle is moving?

    It is hard to press down. When the engine is not running i cant press at all and when the engine is running it only presses less then half way before becoming hard to push and it goes very slowly to floor. I havent tried when moving the vehicle yet as it is still on the axle stand without tyre. Do you think it will be better when moving? I didnt want to put the tyre back on incase I had to re-adjust something

    If it goes to the floor there is a problem. Was the replacement caliper new or second hand? Have you checked over the system for fluid leaks? What was wrong with your old caliper?

    Without a foot on the brake, can you turn the wheel freely when it's of the ground?

    My old caliper was seized. My mate came around and messed about with my landy and now brakes are working good
