How to Retract Pistons

[PapaHoosh]

In case you don't know this I found easy way to press all the pistons back into the caliper. I used a spring clamp.

Cool and useful trick- thanks, "Pop"

Maybe not, his brakes are dragging (in another thread).

Caliper pistons should be cleaned before being pushed back into the caliper (s).

Dirty pistons can contaminate the brake fluid as the dirt breaks down or cause a piston to stick depending on how dirty it is?.

Large channel locks or a C-clamp using an old pad. will draw all three pistons back in at the same time.

Yeah..what Rocky said. I do the same thing...gently blow it all down with compressed air (gently), then spray the entire caliper with Brake Cleaner, then blow dry with air again, THEN.....compress the pistons using an old pad, and channel lock pliers. Also, lube the heck out of all contact points, and slider pins.

Thanks for reminding me Rocky getting ready to replace my pads i do blow everything down with air.

A ratchet style C-clamp (and the old pad) is what I used. I used to use a small piece of wood with a C-clamp, then one day I happened to look down and saw the old pads sitting there, and realized I was missing the trees for the forest.
