ok, my 95 Prelude VTEC front right disc brake is dragging on the pads
took the wheels off
brakes stuff are oem
checked the lines - no cracks - the lines are still flexible and soft
the discs and pads are 9 months old
check the calipers the piston can be pushed in with a C-clamp gently... doesnt seem like a problem pushing in... and it holds it position after it's pushed in... i noticed the rubber piston boot is cracked, so maybe some dirt got in and what's why it doesnt retract when the brake paddel isnt pressed down? or there's a minor block in the brake lines?
think a flush would clear the problem?
or what do you suggest?
and another question.. replacing the boot, the piston can come out completely right?





thx in adv.

 

In order to replace the boot, you might have to take the piston completely out. I think the boot might fit in an internal groove in the cylinder, and the piston blocks you from removing it.

You say the piston can be pushed in easily. If you can push it in with your fingers, that kinda eliminates worries about blockages in the hydraulics or the piston itself.

The other things to check are...
1) Caliper slide pins have to move easily in their pockets. Clean em up & put fresh grease in there.
2) Brake pads themselves, where they fit into the caliper bracket. Make sure there's not a bunch of crud around the pads, and the surface where they fit is smooth. Sometimes I've had to file the top & bottom ends of the steel backing plate on new pads. Just make sure they aren't wedged in so tight that they don't release. Sometimes the thickness of the paint is enough to make them jam in the caliper brackets. Grease there where they slide.

1. thx for the advise
2. umm the piston can be pushed in with your fingers/hands? hmmm i can only do that with the c-clamp... hmm

well, i just bought a caliper repair kit (the rubber boots and the seals) i'll take out the piston and clean the inside see if that helps

But it moves.

 

well, bleeding doesnt help
i replaced the boot, it still grabs the disc
grrrr

and whoever did my brakes last time tighten the bleed screw way to much and it snapped off when I tried to unscrew it... maybe it expanded to much due to the heat... dunno... just grrrr

looks like i have to get a new/refurbished caliper body thing
