Heres a two pot rear caliper that I've refurbed for a friend, along with his four pots, it has been half soaked in brick acid for two days and literally rinsed off (to show before and after). Note the dirty part is still covered in road muck, brake fluid etc



They now look like this



and the fronts (I don't have a before pic )

now look like this



Less chance of blowing the house up with brick acid, not that expensive either! Make sure you use goggles and gloves if using this method!

 

You lot are bloody mental, do you not possess a battery drill and a wire brush attachment.

Bit of nitromorse to get the paint off and then spent an hour or so with the drill, jobs a good un, and before anyone says it, mine looked just like your lots after 15yrs on the car and came up a treat, then I repainted them with hammerite enamel and a brush, but you do have to keep them level to stop runs and put plenty on.

 

Old brake discs make good anodes. You can clean your anodes if you want but that's effort lol

 

Is it worth me refurbing my 4pots and 2pot rears or sell them as they are do you think?

 

Can anyone give me some good prices and places to buy 8 x 4pot pistons? Not fussed if stainless or mild steel as I won't have the car more than a couple of year at most, I just want my brakes fitted now.
I have the seal kit, just need the pistons.

 

Godspeed are excellent, I think it was £50 for mild steel one's and around £90 for S/S inc del iirc.

 

Nice one, appreciated thank you

 

Do the calipers work properyly? If so sell them as there are if not refurb them imo.

 

Picture of them fitted with new pagid discs

 

I've just fitted my new seals and pistons, so here is a proper before and after look

BEFORE:






AFTER:

 

Dave, what kind of paint did you use? Looks like gunmetal hammerite?

 

It's Halfords VHT metallic black!!

I wanted a kind of metallic grey and read the reviews which said the black actually comes out grey, which it did:-). I then lacquered them.

Job done.

 

I noticed i never added picture of my new calipers fitted, so here we go

 

Sorry to bring this thread back from the past am looking to refurb my 4pots again. Last time I didn't do the pistons but will definitely buy a seal and piston kit from Ian

Question..... Is there real need to split them in half as last time I tried I couldn't budge the bolts. If no real need then will sand blast them in my home made cabinet (old commercial glass fronted fridge) but that oxcilic acid looks fantastic.

 

I can't see any reason to split them. But to be honest i wouldn't bother refurbing them either, you can buy a new set for £150. Sell your old ones for £50, then respray new ones job done.
