Rear calipers same as BX front calipers? well almost but no

In the hope of finally establishing a source for these calipers I have looked through all my original paperwork to establish the correct numbers.
Bendix official numbers are 691255B and 691256B. When you order them on the boxes that the parts come in are marked 691255B/L669255 and L669256. These are taken from an official Bendix catalogue. Also today I contacted the following motor manufacturers - Partco, Autoparts and Brown Brothers and was told that part nos.UGCGBC726OE, UGBCGBC7261E are the rear calipers and can be purchased for £80 + VAT. If there is one of these motor manu's near you then you should have no trouble obtaining the parts.
Best of luck

Thanks for the definitive advice Andrew.

I guess there's no excuse for sticking rear calipers now

In need of a new rear caliper for the MOT. Tried a few suggestions on here. Both my local motor factors and Brakes International, Bolton wanted my old caliper for refurbishment. They didn't supply new. Tried Partco, Birkenhead (0151 6477891) in the end. They quoted me £120+VAT for a new one which they'll have in for me to collect tomorrow morning.

I'm just hoping they know what they're talking about and will actually have one for me in the morning! I'll keep you posted!

Well, I drove to the Birkenhead motor factors this morning to collect my caliper. He had two boxes on the counter and after producing my caliper to compare, it turns out neither were correct! Nothing like my OE caliper at all - far too small, wrong size, wrong shape, very cheap and nasty looking and one looked like a front caliper with no hand brake mechanism at all!

So a complete waste of time. When someone tells you over the phone they stock the correct part you need, don't necessarily believe them and take your old part to check.

So I've taken my old caliper to a local motor factors and asked them to send it off to see if it can be refurbished.

Has anyone actually replaced a rear caliper with new? Anyone successfully fitted Citroen BX calipers and if so, off which BX?

Andrew, how did you get hold of a Bendix catalogue? Do you know of any Bendix dealers? I couldn't find one.

Cheers.

I replaced both my rears with Brakes Int for their Peugeot 205T16 calliper....theres a thread out there somewhere about it....and they fitted ok. Simonsays74 seems to think the arm on them is slightly longer than the GTA arm, but its not a massive difference and mine passed its MOT last year with the new ones fitted.....just needed adjusting.

Thanks Peter, I'll bear that in mind, should they not be able to refurbish mine.

Been there, done that

Try RenTek (small Alpine specialist in Weymouth) paid £110 plus £30 surcharge.
They're refubs and excellent ones.

I bought a replacement from Brakes International via the internet for around £120, this compared favourably with Cafco, the local parts factor. The rear caliper is the same as that fitted to the Peuageot 205 turbo 16 coupe - that sounds pretty rare too.

As damien said on the previous page and Peter reminded me, they are the same as the rear calipers on the Pug. 205 T16. I'd completely forgot to try this line of enquiry! So I phoned Brakes International again this morning, only this time asking for a Pug. 205 T16 caliper and they had one in stock! Definitely the same. Handbrake lever slightly different length but fitted back on the car perfectly. £83.44+VAT exchange. (Why can't their supplier/records/computer cross reference the caliper as being the same part for both a T16 and GTA? )

One important thing to note. If you do order a caliper for a 205 T16, order the opposite side to the one you need. The calipers are fitted leading on the 205 but they're fitted trailing on my GTA. So a right rear caliper on a GTA is the same as a left rear caliper on a 205! At least on mine. Don't know if any GTAs have leading rear calipers.

Those calipers on the Speedways web site look correct too Lee.

Cheers all!

Juzz, have you got any part numbers from Brakes International for the rear calipers, rather than just Pug 206 T16?
I too have trailing units, and I am looking for a nearside rear unit.

Actually, I need one, 'like tomorrow (or Saturday) for MOT and Tax so that I can compete on Sunday. Anyone got a spare or can lend me one till next week, would be very gratefull.

Mine failed an MOT today on handbrake, zero on the n/s rear while 100 on the o/s rear. Foot brake recorded 260-280 on each side at the rear. I checked the cable, it is not seized or streched. The cable pulls equally on both sides of the car, I just can't think what it can be, so thought I'd just change the caliper. Any ideas, but I need a quick fix???

Simon.

Hi Simon, I bought an offside rear caliper. Part No. BCA1302

Not sure if it'll be a different part number for the nearside. Their contact details:

Brakes International Ltd
33-39 Bury Old Rd
Bolton
Lancs
BL2 2AY
Tel (01204) 385888
Fax (01204) 438888
www.brakesint.co.uk

I paid £98.04 inc. VAT (exchange)

Hope this helps. Good luck!

This is GOOD.

firstly Mike at Brakes Intnl said that the GTA was special and not comapible with anythng else. I told him of others experiences with Pug 206 T16, he was very supprised, he then tried to sell me a BCA 1303 as the opposite side to the BCA1302, which contradicts Stuart D's post on previous page stating the BCA 1304. Oh well......

Seconly, I fixed it with out any parts.
Reason for Refusal of MOT was handbrake, o/s 100 and n/s was zero.
I checked the cable and it was nice and free within the sleeving, I also emmeried off the glaze from the disk and the pads. Retest showed 40, still a fail.

Now here is the GOOD bit, as suggested by the tester/foreman.

Remove the handbrake cable, remove the pads, wind in the pistion (as if you were about to fit new pads) replace pads, pump the pedal, then afterwards reattach the handbrake cable. This 'resets' the caliper .

This might sound to be off the wall, but on the 3rd attempt, it registered 100 and he was only looking for 60-70. Pass at last.

I wonder whether its the action of winding the piston in/out that does the job here, rather than any resetting action. One of my calipers has got dodgy outer seals on it and every now and then, I have to wind the piston out, clean off some crappy white deposits and then wind it back in. Normally put a little grease in there as well although I know thats not the best as it can attack the seals.

The symptoms are exactly the same - footbrake works fine but handbrake does not have enough oomph to move the piston. As soon as the piston has been freed off - the handbrake works well again. The piston is usually very hard to turn at first but then gets looser as you work it back and forward.

Do you find your GTAs have too much front brake bias?

I have a new master cylinder, rebuilt calipers, new braided stainless flexible lines, with EBC Greenstuff pads all round on new discs, all bedded in, and still I find a tendancy to lock fronts more easily than I would like.

My 405 Mi16 would whip the GTA in stopping contest. I have since removed the rear brake pressure regulator valve, and inserted a T piece with a noticeable positive result, but could still do with more. Did Renault just get the size bias wrong in the first place?

My wheels and tyres are std, with the tyres being of good quality, and of equal age. I am not dissapointed with the handling, only the brakes. Perhaps when I fit a set of wider wheels, and stickier rubber all will be solved.

Actually just thinking that if I upgraded the spring (or put a couple of washers under it) between the back and the front pistons in the master cylinder more pressure would be applied to the piston furthest from the pushrod. I wonder which piston is for the rear. I know the brakes are split front/rear, rather than diagonally like most cars, because of an unusual weight distribution.
