Has anyone got anything light and small for the back of my car, I've sierra calipers at the moment but looking something lighter that will pass
mot..
Thanks.
Peugeot 106/205/306/309 rear calipers, if you can come up with a way of fitting them.

pug calipers are not 2 pot, they are single. They are also shockingly poor as handbrakes.
Arent golf callipers popular? Not sure if thats cause they are light or just readily available, or both?
Edit also didn't realise they were 1pots

Absolutely nothing wrong with floating callipers, that they are inferior to traditional symmetrical type is a bar room myth. Girling developed the
"Colette" pattern floating calliper which is the type most modern designs are based on in the 1970s to reduce unsprung weight
Floating rear callipers with built in handbrakes just need careful setting up to give a decent handbrake, some models suffer from poor handbrakes
because the linkage isn't stiff enough.
Should have said guys I'm looking for an aluminium caliper.. I've already got new sierra caliper on there but they are very heavy!
Hi Benzo,
Pug/citroen rear calipers are alloy, avaible in 30 or 32mm dia piston.
Some Renault use the same too.
Perhaps issue is this caliper work with 8mm tickness discs.
I work on this setup for live axle.
hope that help.

The OPs car is bike engined this implies the weight bias is towards the rear requiring large bore rear callipers rather than small ones. MG TF callipers are in the right ball park bigger bore but only slightly lighter than Sierra.

I should ask.. Has anyone get a pair?

I've been told I need little braking effort at the rear and when I used sierra rears I had to sinificantly turn the down.
This time I will be running dual circuit bias pedal box, not a bias In line valve.
I'm looking for weight saving and I have another use for my sierra calipers.

have you tried the VAG group rear calipers? bolt up to sierra mounting holes and some are ally. They are sliding single pot and come in various bore
sizes, still overkill for a 'fag-packet' BEC, but less so than sierra or aftermarket 4 pots imho
ive used some and the Raldes versions and the problem isnt so much with the handbrake mech as the lever. we all use handbrake lever setups designed
for drum braked cars (escorts, sierras etc,) and they dont have the throw/mechanical advantage required, to go over centre and lock the calipers. I
played about with extending the cable point on the handbrake lever itself and certainly helped a lot although being lazy i never perfected or persued
it as it was a track-only car

I have a pair of new HiSpec SVA Ultralite HB Sierra lug mount rear calipers for solid discs with handbrakes, cables to suit and Mintex 1144 pads. I
was asking £300 but would accept £275 which I believe is a saving of over £125. Could probably do a deal on just the calipers if you were
interested.
Cheers David

Do the maths
Even with a Pinto engine these cars have as light rear weight bias with the driver on board, looking at your photo archive your car has little static weight carried on the front axle, that means under braking your rear brakes will have to do between 33% and 40% of the stopping. Contrast this with the Sierra donor where the rears only do about 25% of the stopping.
For the small amount saved it will be an expensive exercise to swap to lighter than the Sierra ones , as above the hi spec ones would suit the job
although will cost .
Mechanical handbrake calipers of any type are all prone to issues with performance although a lot of that comes from maintenance and lack of it
although I am referring to tintops in regard to this which rarely see the maintenance of most 7 type cars .
Westfield of course went from Ford type to VAG type alloy calipers (single sliding again) and is worth bearing the VAG type in mind although not a
favourite of mine.
If you are looking for MOT compliance , are you running an LSD , of course if you are the car will have to be tested with a decelerometer and not a
roller brake tester and my personal opinion on this is that very few cars fail this ..........
Sorted with something now, Thanks.

Yer Benzo what is your set up for future reference??
My rear brake is going to be a nightmare as im running fiat coupe hubs...... Been thinking about a nice light weight alloy twin pot too.
Bought some of these to try..
