Help getting my calipers off? :) - Sorted!

Well, mine is a wire brush and not a drill attachment, so had to give a good 10 mins of elbow grease to get it to what looked reasonable. Would you suggest any chemical cleaners to make sure the surface is 100%?

If it's a strange size, that would completely explain it! I've never needed the 7 up until today, so didn't think of it. What were Opel thinking in that design? heh!

How would you push the piston back without removing it? Maybe I'll understand when I take another look tomorrow.

Thanks mate.

Use something like a bar to lever the piston back.

Also, remove the cap from the brake fluid reservoir, it helps relieve the pressure you are causing in there by pushing the pistons back.

Oh, I thought removing that would have it spew out all over my nice clean barn floor (lol)

Thanks for the input guys! Greatly appreciated

Thats where people go wrong, with new pads and disks top the level up, then as the pads wear the level will drop, this shouldnt be topped up again, as when you push the pistons back it goes everywhere, instead of going back to the full mark. There is enough fluid in the resevoir to allow for wear.If you DO need to get some fluid out, either bleed it off first or gt some clear piping and suck it up the pipe, SLOWLY as not to get a gob full.

But if I topped it up, would it not then go everywhere when i pushed the pistons back?!

Don't top it up then :roll:

Well, naturally - that's what I thought also.
However that reply was in response to callymat's somewhat confusing suggestion!

I didn't find it confusing just common sense really, Only top up reservoir after discs and pads have been replaced.

also (I dont think anyones mentioned) ..... dont forget to clean the anti rust stuff off the new discs before fitting them aswell, meths or petrol will do an adequate job of this if you dont have brake cleaner to hand.

Robbie, took 2 reads to get it, I'm still not switched on upstairs.. do forgive!

MJ, they felt well slimey tonight, but I thought the blocks removed that - whoops!
I'll clean them tomorrow.

Many times, I have one in PDF on my laptop.

Ok! All finally sorted!

It took;
LHS: 1.5days
RHS: 20 minutes

LOL!

Went for a test drive, and it feels wonderful to have working brakes again.

Anyone care to offer some "Wear in" tips?
Don't want to warp them :s - Seems very easy to do!

no hard braking for about 50 odd miles

**DC 12v** · by **DC 12v** » Wed Sep 03, 2008 11:37 pm

80km.. well, I'll be covering 2x that tomorrow, so by the time i'm back - they should be nice and worn in!
