Hi hope someone can help just had my brothers marea in for mot failed on brakes the car is a 97 2.0 20v
so we put new discs n pads on all four corners went back in for mot failed rear brakes not working so we bled them still not workind so we did a full system bleed still not working stripped and cleaned the calipers (lucas) still nothing :bang:
ps abs working fine
i dont understand ive had 3 2.0 20v and never had this b4

Does 2.0 have a braking force regulator (would you call this part that?) around the rear subframe?

It may be stuck or rusty and might need replacement.

i know what you mean, not sure of the correct name though.

i'd say there is either a leak or a crimp in the line.

Part you're thinking of is the compensator valve and yes they do have them and yes they can cause poor rear brakes. Replacing isn't easy but will probably fix your issue.

Thanx for the help ill have a look at that then (anyone got a ruff idea of where it is)

Just follow the brake lines from rear wheels - they meet in this device and it is mounted on the rear suspension subframe.

Thanks alot will change it

You might be able to fix yours. Give it a thorough soaking to release the pistons and check the spring is still attached and in good order.

on this model it is a load sensing proportioning valve. it is fitted to the centre of the rear beam. you can easily remove it to check if it is working correctly. the valve may simply be stuck in place, or the load sensing part has become disengaged allowing the valve to close. however if you could bleed both rear cylinders easily enough it would suggest fluid is passing through the valve ok, but at the same time that would not neccessarily mean the rear breaks are getting enough fluid to them to pass an MOT.
