Quick question - specialized caliper tool needed for Z4M brakes

intoflatlines · 01-06-2015, 02:12 PM

I plan to replace my brake pads this spring but I'm not sure if the Z4M brakes require a specialized brake caliper/piston tool or if I will be OK with just a universal tool.

do yourself a favor a use a huge assss c clamp to compress the piston. mind the sensor though

no special tool required.

RE: BBKs though...

I bought a spreader on eBay but it's useless because the spreaders angle slightly inward resulting in pistons not being pushed in 100%. In other words, cheap crap.

How do you guys do it? I've read people use screwdrivers and paint scrapers, but doesn't that scratch the disc while you lever against it?

I used a C-clamp to fully compress the piston before removing the caliper, and then this to push it back in just before reinstalling.
They sometimes sneak out a little after you compress them.
Especially on the rear, because I was fiddling around for a long time replacing the parking brake shoes.
