Hello, firstly i want to say hello to everyone on this forum and also want to apologize for my english. I tried to find a solutions on forums in my language but there is nothing to find, so i decided to ask for jelp here. I have a problem with rear brakes, they doesnt work like they should. Front brakes are braking perfectly but the rear brakes are braking verry poor. I made a regenaration of clamps at the back, brake disk and pads are okay, elastic fluid wires are good too. I saw only one issue, the fluid pressure is verry low. At front brakes the fluid is squezzing when i push pedal but in rear brakes its only leaking. So after few kilometers front brake discs are verry hot, much more than back discs. Anyone know how i could fix that issue?

 

First thing to check is pressure for rear lines at abs module.

Have brake fluid changes occured regularly?

 

I have a tool to check compression on pistons, can i use it to check the pressure on abs pump or there is a much bigger pressure than it can check? Is there a something like brake force corrector between pump and clamps? I bought this car 2 months ago and i changed the brake fluid. I think the
Previous owner of this car didint change it for a long time, there was a white foam when i pumped pedal to get the air out from brake wires.
