How stiff is yours!

[garyholden]

I've just refitted my caliper pistons after stripping them and replacing the seals. I'm not sure whether they are free enough. How stiff are yours? Can you move them easily?

After all the work with the front and rear breaks is there any way of testing them? The only way I see is to put the body on and connect the pedal box and master cylinder etc.

Be a shame if it didnt work after the build. Wouldnt be able to wait to take the rear calipers of again.!!!!!

Any thoughts

I didn't refurb the callipers on my car but I have done them in the past and they were quite stiff as i remember but they did go in OK if I applied FIRM pressure on them. HTH

Having spent the saturday and some of sunday stripping down and replacing the seals in FOUR sets of calipers I can say that the pistons when the calipers are rebuilt should offer offer firm resistance to hand pressure.

To check the seals after I rebuilt the calipers, I filled the calipers with fluid, and then put some air pressure ( cheap ALDI compressor 7 bar) onto the end of the fill pipe, thereby pressurising the cylinders. I also made sure that there was no danger of the pistons popping out by putting a wooden spacer between the pads.

If theres a leak on the new seals it'll show up then.

Cheers,
