What did you buy today

[mudski]

Awesome to hear..
Struggling to find gu rears though. They all show 4 sets of seals even though they say "rear" in the add..
Any idea if gq calipers are the same as gu rears??

Gq is different to gu mate.

4 seals for twin pots. Ever done brake calipers before?

no idea about the rears being the same.

Just did fronts today mate. Theres a trick to getting the dust boots on and around the pistons. But took about ten minutes a side after they were prepped for the rebuild. I took heaps of pics and was thinking of doing a walk through thread.

Trick to get the pistons out, use compressed air. In little squirts other wise they go flying. Try stop them completely coming out as it will only push 1 out, then be a pain to get the other side out.

To get the dust boot back on, i put the boot onto the piston but around the middle, not in the groove yet. Then seat the piston in the caliper and tuck the lip on the boot in the caliper. Easier to start at the side that is hard against the caliper then finish on the open side. As you push the piston in, keeping the boot out the way, slide the boot up into the groove then drive the piston home.

Words are not my strong suit. Hope that helps.

Yea I guessed that. Thus the set of 4 seal lol..
And no rears are only single pistons..
I have done a set before. But back on the farm when I was like 12 with grandpa lol

For the twin potters I put a piece of wood over both pistons and then a g clamp to hold the wood. Slitghly loosen the clamp a little and use compressed air in the brake line port. Both pistons will move together. Loosen g clamp a little more and repeat until pistons come out.
As for the boot i slid the boot right down until its hanging past the base of the piston, then push in the section ofthe boot into the caliper housing groove, once in, push the piston in.

That works. I have found that the boot is easier to pinch while trying to get the piston in, but in saying that there is more then one way to skin a cat, and my methods aren't always the best

Watched a few vids to freshen the memory. And yea wood packers to slowly eject the piston with compressed air..

Exactly! When I first did a caliper I put the pistons in without the boot on the had a hell off a time trying to get the boot to clip into the housing... Lol. After experimenting a few different ways I found this took about a minute to do....

Here's some pics that may help.... I actually used the old brake pad instead of wood for this one.




I had the boot over hanging the base of the caliper and this made it real easy to get the lip of the boot into the groove.



Once in I just carefully pushed the piston in...




Just remember the orange grease is for the slide pins.... I have a 500g tub of the red rubber grease so I used that instead of the red grease supplied.

Cheers. Yea I have a tube of rubber grease at home to that I planned on using.
Top idea with the pad. I'll be swapping them for bendix pads so don't care if the old ones get damaged..

Do tell please go on Im enthralled lol

Where was this post a month ago when I was needing to rebuild mine?!?!?
