Hello,
I have a strange issue that I am hoping someone can shed some light on.
My left rear caliper will effectively stay on when you use the brakes a few times and will release itself but only after a few minutes.
It is not a sticking piston. I have removed the piston, cleaned it, it is in very good condition and I replaced the seal.
The strange thing is that as soon as I open the bleed nipple a little the caliper will release. So the piston moves back when the pressure released and that is why I am saying it is not the piston.
I am not sure what is happening here. The caliper seems to be in good working order but pressure is building up in the caliper and slowly releasing.
Its as if something else is causing the pressure not to release, something further back the line. I have replaced the rear hose to eliminate that.
So what else is causing this? Can there be something else wrong with the caliper? There is not much to them.
Another thing I should mention is that when you remove the caliper the fluid will not flow. If you press the brake pedal it will spurt out, but without the pedal pressed there is nothing flowing. Could this be related?
It is as if something is making the fluid stay where it because you you cut the pipe, which I did, the cut section is full of fluid and it pours out but the section still attached to the car retains the fluid.
This is only affecting the left rear. All others calipers are fine.
I have never seem this on a car before and I have replaced a few dodgy calipers in my time.
Thanks
Barry
