4 Pot Caliper refurbing
I didn't realise how bad my brakes were until after driving in a none turbo and nearly going though the window screen when breaking
I'm going to have ago at refurbing them myself, is this wise?
I've seen a few company's online say do not refurb yours calipers by yourself, trying to scare you off.
But saying that, its properly because they want the work. Any comments?

Did my rears thursday. Straight forward enough. Getting the new pistons back in was hard work till i rigged up a homemade clamp. Good opportunity to flush all your old fluid out too. Got my refurb kit from scoobyworx.

Get the calipers shot/grit blasted,clean up the bores not sure if you can get them shot blasted though,mask the bits up that shouldn't be painted and get them powder coated.
the price of shot blasting and powder coating is very cheap imo (recently had an inlet manifold and H brace stripped and powder coated for £50 cash )

yep they are all shagged. when i get in the scoob after driving the bm all week i have to force the pedal down hard to stop. they are good brakes but the servo assist isnt the same as a modern car.

It's up to you, but think that those little pits will rub against the seal, and that seal saves you from hitting a wall. For what it costs for some stainless (or Ian at godspeed may be able to help you out with some standard non stainless pistons for less than the stainless) its worth doing for peace of mind, and you won't have to do all this again.
What I did was buy some oxalic acid from ebay - http://www.ebay.co.uk/itm/1kg-Oxalic...item1e6cad1a49
Whack them in that for a week or so. Take them out, rinse them and then use a wirebrush. Mine went from this....
To this once primered....
And yes, when you spray leave putting the new seals and pistons in until last, and spray with the old piston's just sitting inside the caliper.

I wasn't going to brake the calipers open as i've heard they can be a pain to seal up?
Can't see the need to either.
Good call on that Oxalic acid Cleaner & rust remover, looks the thing i need
Will replace all pistons, no point doing half job

See if you can spot the obvious mistake and talk about overspray
