Stripping back brake caliper
 

I think that my caliper has seized on the back.

So, I'm going to have it off, strip it down, and regrease / lube everything up.
Its a K3 pointy SV.
I seem to remember someone did a picture guide?

What bits and bobs do I need? Red rubber grease? I'm going to get them all checked by a clued up mate once I've done it.

Any weird bits of kit or handy tips you have found out the hard way, gratefully received!

ETA: Found the guide: http://forums.sv650.org/showthread.p...ght=brake+pads

Rofl, Are you going to create a thread asking how to put petrol in next? ;)

Done mine las week, a bitch of a job if like on mine,everything is seized.

Try to loosen the main 2 allen bolts that hold the caliper together before removing from the bike.
Even though i had the correct size snapon allen socket wouldn't budge.Next tried loads of heat,no chance so tried a breaker bar,and just rounded off the bolts.
Out comes the hacksaw,took ages as they are big old bolts. Then the grinder to tidy up and get rid of the remains.
Back with some heat and a hammer and punch and finaly they came apart.
Again more heat and mole grips to remove the stud thats left in.

Oh yeah i forgot,before i did that,i had to do the same with the pad pins.

You don't need to grease your brake caliper!

It depends why you're rear brake doesn't work, Personally, I think you've knackered it with all that ACF50 you've been spraying (A WHOLE can?!) if it is ACF contamination, you'll need:

New disc, new pads, some fresh fluid (You'll never get ACF off of a disc, and your pads will be contaminated)

If it's seized, you'll need new caliper seals, some brake cleaner, and brake fluid

You use copaslip on the backs of pads where the pistons touch the back of the pads, this is to stop the pads chattering as you brake, NOT as lubrication.

Use clean brake fluid, if anything, to lubricate the piston seals.

You do in fact need some red rubber grease on the brake seals, well you don't have to put it on but it may help them last longer

you can also smear some on the pistons as well

I got the seals kit and pad pins etc from wemoto.com. They include a small tub of red rubber grease in the kit.

I've a tub of red rubber grease, no point buying a pound of it to do one caliper. PM me and you can have some for the price of postage, don't expect instant delivery though I'm busy with exams atm.

Right then, for the rear brake, it can be a bit of a git.

Pointy is a single pot caliper which is easier.

All you need to do is remove the pads, pump the piston untill it comes out. Remove the seals, scrape all the crap out of the seal recesses, thouroghly wash and wipe out the caliper with brake cleaner, pour a little fluid into the reservoir and let it run out of the caliper, wash it again. Let it air dry, brake cleaner dries pretty quick.

Clean the piston with something non-abrasive, the green scourer things are alright, they aren't harsh enough to score the piston.
Wash the piston in brake cleaner, allow to dry.

Then, wipe some red rubber grease around the inside of the seal recesses, put the seals in, put the piston in, then remove it again and wipe excess rubber grease off the back of it. Wipe this excess around the walls of the piston. Slide it right in, bit of a wiggle to get it moving and it shouldn't take more than thumb pressure.

Wire brush the back of the pads and other gubbins, wipe a little copperslip onto the back of the pads and reinstall. Red grease is better than nothing on any sliders which have rubber sheaths like on the front calipers (I'm not too familiar with pointy rear brakes)

Then bleed it through.
