Default tough brake pads and caliper pistons..

Any suggestions on how to more easily remove old pads from the caliper..they can be very tough to pull out..also to make room for the new pads, how to depress the caliper pistons? suck out some brake fluid from the reservoir then press hard?

I pry against the pads...or use a big pliers against the "ears" of the pads.... to push the caliper pistons inward so the pads can be removed. It really should take much effort to push the pistons back

The there is a bie wear "ridge" on the disc it'll make pad removal a bit more difficult as will stuck caliper pistons....which you might have. Very common.

Cheers

Open the bleeder and wriggle it back in. It's a very close fit so if it's even slightly cocked in won't go back. If the bores are rusty it'll be that much harder.

The bleeder is the nipply-thingy at the top of the caliper.

If you don't want to open the hydraulic system you can try pushing the piston back with the bleeder closed....but it might be easier with it open.
