Ian,

I have a 22B which like type rs and some ras has two pot rear brakes which have a disk surrounding a drum handbrake.

I am hoping to be able to modify the rears, mostly for aesthetics to be honest as I would like a nice 2 pot AP or brembo caliper, and if possible an uprated disk.

I don't really want to destroy the brake bias, so am not looking to change diameters or anything.

Do you do anything which would be suitable, or have you done anything before to such a car?

I remember reading somewhere that some people junked the drum brake and went for a standard type disk and bell arrangement and changed the handbrake drum and shoes to a handbrake caliper.

If this hasn't been done before, do you think you could take it on as a development project or even a one off?

thanks for the help

If its for looks you are going for , you could always have your calipers reconditioned and sprayed , and ehem , put a name sticker on them to make them look something else , there should be something in the brembo or AP range that will fit , I will look into it for you

Cheers Ian

actually the standard drums tend to rust and look terrible.

The car is otherwise pristine so it does ruin the whole thing.

I have AP 6 pots up front right now, so would like some nice AP 2 pots at the rear. preferably in black.

I could supply you new rear discs , grooved which would be zinc plated , where the pads sit would wear the plating off straight away but the rest of the disc would stay plated and wouldn't go rusty , I can have them plated gold or silver , the rear calipers you have are alloy and you would get no gain in going for AP other than looks , but we could recondition your original ones spraying them black to look good

Cheers Ian

sorry, perhaps I wasn't entreily clear.

Its the drums which support the disk which are rusty, the disks themselves are fine. The calipers are red at the moment I think because its a 22B and not a type r. They are not rusty at all.

Converting to bells would be the best solution, but for the name I am keen to go for an AP 2 pot caliper if it can be made to fit the same location.

If you can remove the bells and make those nice and clean and then zinc plate them, that might work well.

Getting a bit mixed up here , do you maen the centre of the disc , if so it's not separate , You cannot get a 2 piece disc and bell to replace the standard ones , When I say we can supply a one piece disc which is plated it is done to stop the centre of the disc , the bell from going rusty.

The calipers wont go rusty on the rear as the 2 pot subaru calipers are alluminium , the fronts are cast steel.

Here is a pic of the one piece and the large 2 piece rear discs we supply , the large kit is only for the early Impreza up to 2000 with the sliding single piston calipers .

I didn't realise it was one piece.

That large kit looks far nicer than what I have, and if zinc coated it wouldn't rust as you say.

Why is it specifically for the sliding caliper? Can you not fit it to the two pot caliper?

Also you mentioned you could find something for cosmetic reasons, do you think you could look it up for me or are you unfamiliar with the type r set up I am talking about?

Adam, if Ian has done the kit for sliding calipers the internal dimension of the bell will be 170mm dia. to suit the r160 diff parking brake. Yours will require 190mm dia. being an r180 diff.

Could done i guess, but then the bracket to space the caliper out (the discs are 320mm) would have to be made too.

Actually the internal size for the hand brake is the same on all the rear discs , but the discs are bigger at 190mm rather than the 266mm ones , I have not done a disc and bell kit to suit the 2 pots yet but it's something I am looking at , hopefully soon it will be finished and available

I'll have to disagree with you there Ian. There are two sorts of 290mm disc. Ones to suit the r160 rear diff arrangement (i.e My01 wrxs) and then there is the ones to suit the r180 rear diff arrangement (classic type R, Ra limited etc).. i.e 170 or 190mm internal dia. I've seen pics of the two types of discs from our friends over the pond, there was definately a difference. Maybe as with all things Subaru it's not always as clear cut as that tho .

Anyway, forget the discs i still haven't got my bolts and spacers . My front caliper now moves around due to the bolts. Looks like it will be off the road again . YHM yesterday.

ok, so aside from that, I am still a little confused with all the dimensions flying around.

The 190/170 refers to the diameter of the handbrake, and the larger numbers refer to the external disc diameter.

Ian, I am a little confused also by your "but the discs are bigger at 190mm rather than the 266mm ones " comment.

where are these 266 and 320mm dimensions coming from?

Confused , so am I

The Impreza rear discs up to the bug eye had 266mm rear discs on , the type R and 22B had 290mm discs , the bug eye onwards also has 290mm discs , basically if you have single piston calipers on the rear then they are 266mm , if you have the subaru 2 pots on the rear they are 290mm.

I have supplied the same disc for the Type R and bugeye which has different diffs sizes so I am a bit confused now in what tony is saying , I will have to look into this again

The 325mm rear disc is one that I make to use with the sliding single piston caliper

Hopefully this makes it a bit clearer

Cheers Ian
