Sticky caliper on 4 pots, new seal kit or piston?
 

Had my front 4 pot caliper off today to try and solve a binding issue. 3 out of the 4 pistons are moving freely and 1 is sticky but it did move back in with the use of a clamp.

Is it worth fitting a new seal kit? I'm hoping to save the caliper and hoped that would work.

Seal kits are cheap now but the issue is more likely rust on the piston or the inside of the caliper, maybe even both. It's easy to take them apart and clean them.

Thanks, I'll take another look and see if I can strip the caliper down. I take it I'm ok to clamp the brake line when removing the caliper?

Yeah, just be careful not to damage the line though.

A lot of people tend to upgrade the Pistons to stainless steel ones,so if you're refurbing them it might be worth considering.

Couple of recent posts regarding s.s pistons and calipers. Its interesting read

I've done quite a few sets of 4 pots and the seals usually clean up perfect. I've never had to change them, they always look spot on with a wipe over.

Regarding the Pistons, you may get away without new ones. I did a set the other day and out of 8, only one was actually pitted and I replaced it. It was however totally seized in the calliper and I'm more than used to stripping them but this one was really in there.

Is GodSpeed the only place to get the stainless kits?

We make our own pistons , i'm sure others do .

We have pistons and seals on offer at the moment for £99.99 plus P&P

Cheers Ian

Thanks for posting Ian :) Is there a code for ordering them for that price? They still show as £119 on your site (assuming I'm looking at the correct kit).

Thanks :)

That seems good value, I'll let the garage look this week and see what the outcome is. I don't think I can brave taking the caliper apart myself...

Sorry for jumping in, how much are your brembo conversion rear handbrake inserts Ian? I have the large shoes but thinking the inserts might be better.

Maybe best sending them to Ian?

We can supply you inserts to fit to your discs , but you will need to get your discs drilled to bolt them in , inserts are £125 a pair.
Or we can supply you grooved discs with inserts fitted for £199
Cheers Ian

I actually have a new set of your discs sitting here that I bought in a group buy last year. I'd probably just drill them if you could give me the measurements, or shift them on to someone else who doesn't need inserts. How much for delivery to Belfast for both options?

As regards clamping the brake line, don't do it if braided lines have been fitted.

Bleed nipple size
 

Can anyone confirm my suspicion on bleed nipple size? I am refurbishing my 2001 wrx calipers next week (the non-brembo 4pots) but there's 2 sizes. M7x1 and M10x1. I am fairly sure it's the M7 items but I would appreciate a confirmation.
Cheers.

M10x1 for Brembo and M7x1 for the Subaru caliper.

Thanks. :luxhello:
