Brake caliper seal kits

Where to buy them from?

Anyone got recommendations? Loz?

Its time to rebuild both front calipers on the Africa Twin, so expect a
"Tinkle, Crunch, Ooops..." post shortly

 

Honda dealer for Hondas

Suzuki dealer for Suzukis

etc

I dunno if you've ever done a multi-pot caliper before, but remember to
ease out all the pistons simultaneously, using G-clamps or similar to
block the ones that are moving too far. And rebuild one caliper at a
time, finishing it completely, including bleeding, before you start on
the next.

The nightmare scenario is one or more pistons stuck fast, the others
out, and no means of shifting the stuck ones because there's no
hydraulic pressure.

Then it's down to grease gun time or - if you're really brave/stupid -
compressed air.

I agree. I don't piss around with brake seals, I buy genuine parts every
time. Brake pistons are a different matter, because the originals are
generally expensive and liable to corrode again and stainless steel
replacements can be made.

I've used air *loads* of times. It's perfectly safe if you wrap the
caliper in cloth to stop the piston firing out.

If you've got one piston left stuck, I find placing an old piece of
rubber innertube over the bores for the vacant pistons and 'G Clamping'
a piece of wood onto the caliper will allow you to blow the remaining
piston out with air.

 

I used a diving cylinder to push out a piston many years ago but I was
really wary of it and made sure I was using it off the 1st stage and
choked the air back until it just moved the piston.

 

Sorry, I actualy meant to add the word 'careful' to that. I know lots of
people use air OK. I know lots of people have also been surprised to see
how far and fast and brake piston can travel if unrestrained.

I bought my Genuine Honda items from my local friendly MOT tester.

 

The Older Gentleman? He'z just ziz guy, you know?

Ah, I thought there would be third party cheap mail order places. I
gather they're false economy.

Never done any pot calipers before, got to start somewhere.

Check. All seems common sense so far.

I gather its a case of figuring out which ones are "sticky", which ones
are free, and getting them as far out using pressure as possible, and
then popping the stickiest one out first.

Well I don't possess a grease gun, so I guess I'm with stupid.

Oh, it's only experience that's taught me to be careful. I've had
pistons ricocheting around my garage in the past...
