Brake Caliper Questions About Disassembly

[Hoomgar]

I am trying to pull the main pins out of my calipers. I don't want to use excessive force but the manuals appear to be telling my they just pull out.

I have the rubber boots off and the fittings out and all fluid drained. But how do I get these things out? Am I missing something or do I just need to pull harder?

calipers

do you mean the pistons Mark?,if so it is best to pop them out under fluid preassure before you dismantle. if you mean the floating pin pivots,they are under suction via a rubber boot inside.

That's what they were telling me with the air compressor. Now I get it

pssssssss pop!

They are out

Now, what is best to clean these bad boys with that ownt attack the rubber seal?

pins

they have rubber orings on them and they get hard you should be able to pull them out, if there open on the back side you can use a punch to dive them out, a wood dowel would be best, as long as there unscrewed all the way,a little wd40 in the back side may help

Re: Brake Caliper Questions About Disassembly

I am trying to pull the main pins out of my calipers.

I'm looking at my manual, and don't see any 'pins'...do you mean the bolts that hold the caliper to the bracket on the fork leg? they do function as 'pins' also...allowing the caliper to float.... they should just pull out, try turning them counter-clockwise while pulling

Ahhh, Earl already answered that in the other thread too.

I just needed to read, mineral spirits.

Thx guys, Earl


I'm off.

Sorry guys, I meant the main pistons.

I am a moron, off to work now LOL

guess you meant the piston...use Brakecleaner, before re-installing lube with compatible brake fluid, but don't leave them soak, they'll expand and you won't be able to re-install them, just a light lube and assemble

Use a C-clamp to help push the piston back in, so you can fit the brake pads in properly.

I used to do that for car calipers, these are so small I just used a pair of channel lock pump pliers


I got them apart and the seals look good and I have cleaned both front and back. The boots need replaced and I will order some of them later.

It's weird though, I am not sure what Suzuki was thinking but they made the back brake a dual piston caliper and the front brake is a single piston? That's backwards if you ask me?

I agree. 70% of your braking power is up front. What were they thinking?
