what other brake calipers ?

[bikerzx7r1981]

I'm having a rela problem on the front brake calipers, not only are they no bleeding properly, there also leaking.

I was wondering what other calipers will fit directly onto the forks? Will the gsf 600 bandit or gsx 600f/gsxr calipers fit?

Any help much appreciated

You're making me work too hard... http://www.thegsresources.com/_forum...d.php?t=140253

Are you certain your calipers are beyond the point of saving? Maybe you just need a rebuild.

Hi,

I agree with Mr. Turtleface. Unless your calipers are junk, new pistons and seals (caliper rebuild kits) will do wonders. I'd get new crush washers for the brake lines too. And maybe even some speed bleeders.


Thank you for your indulgence,

I tried the easy option first as have loads of other jobs on this project to finish and the sun is shining...rare in england!

I have changed the brake master culinder as it was damaged.. I used a brake master cylinder from a gx600f, when i put it together the pistons just wont com out.

The bleed nipples were siezed, so I bought banjo bolts with built in bleed nipples.

I have pulled the rubber out and the pistons look completely scored. and full or crap.

The outside of the calipers are all scored to, and one of the bolts that holds it on has just snapped.

Not sure if it time to buy something newer, rather than pour money into ones that will look rough.

Money is tight, as this is a bit of a money pit project

Yeah, those sound sorta rough. There are probably a few people here who would still try to repair them. The link Nessim posted is probably the easiest way to go about adding more modern brakes to a GS. Many people here have that set-up, and many miles have been put on these set-ups, with no ill effects. You'll need to have some brackets fabricated, but you'll run into that problem trying to change over any brake system. If you're concerned with aesthetics, you might go ahead and clean the new calipers properly, then shoot them with some VHT caliper paint, and bake them @ 200 degrees for an hour or so. Here's how my stock calipers are turning out:



Note that normal spray paint isn't going to have the necessary chemical resistance to stand up to brake fluid. Neither with the VHT stuff, unless you bake it first. Braking heat will do the job, but the paint will be pretty soft until then.

How's the chemical resistance of that paint? VHT engine paint has almost no chemical resistance so hope the brake caliper paint is better.

fr t. caliper on 450

Finally got new line for frt. brakes on project bike. Couldn't seem to get frt. brake to bleed, could get about of 1/2 inch of fluid to come out of caliper and into clear bleeding tube on nipple. So took off the caliper (which I bought off ebay a while back) and it didn't seem to be moving. Took off and could not get piston to move. Tried air compressor and pulling out, finally had to use pipe wrench to at least get it to turn and was able to pry it out with screwdriver and finally visegripes. Didn't seem to have much fluid inside piston chamber, but not much gunk either. Piston was in good shape, except for one-two small rust spots. But of course I tore the boot getting it out (there was quite a bit of dried gunk to the caliper channel for the boot.). Tried to put back together just to see is piston was going to move now, got it back in with boot back on piston and caliper. Used quite a bit of brake fluid to lub., but piston still didn't seem to want to move. Ordered new piston kit. Any reason to think this won't fix the problem? Just worried since piston wouldn't move after cleaning and lube there maybe something wrong with caliper. Sorry for the long thread.

Sorry, for my thread in here. I thought I had hit new thread. terrylee

Sorry guys! I thought I hit new thread, didn't meant to put in here. terrylee

I should have bracket sets for the Kawasaki Calipers in about 3-4days.
