Right here's the problem guys, Really stumped!
As some of you may know i have been trying sort out my Subaru 4 pot brakes due to lack of power when braking hard.
At first i had just a re-bleed as the fluid was really old, and this did improve them slightly but i was still not convinced or had any confidence in them so i decided to strip them all down and replace all the caliper seals, boots and front pads etc, along with a repaint and de-rust. disc's also purchased on front.
So today Mr Crowman came over to re-bleed the system with me.
System was bled a fair few times from, passenger rear first, drivers rear, then passenger front and finally drivers front. also bled a second time round in a diagonal pattern after reading a few things on the net.
After we took the car out our initial thoughts of the pedal being spongy was that they need a good 300 miles brake in and but as we braked every second time round the pedal got harder and the brakes responded brilliantly, even getting the ABS to kick in which i never was able to do before.
But here's the problem, the pedal goes back to being spongy again once released and you carry on driving? its like fluid is letting by somewhere and it takes the second pump of the pedal to make the brakes work fine???
Have checked all around and have no leaks from anywhere, levels are stable in the reservoir and don't move, all i can think of is the master cylinder has a fault within it, ABS, Servo??, don't really know what else to check, pull apart or where to look?.
Any input would greatly help!
Might jack it all in and go and buy a white spec C
