As part of a uni project, I need to look at differing brake calipers. Does anyone know of manufacturers apart from the ones I have listed below please?

Brembo
Nissin
Tokico
AP Racing

cheers

There are loads of makes, it just depends how mainstream you want to stay.

A main one you've missed that springs to mind is AJP. A lot of the European bikes run these.

More specified brands out there, such as Wilwood and Harrison Billet. Probably more but cant think of any off-hand.

Sumitomo make calipers for Yamaha.

Thanks for all the replies Thumbs Up

. I wasn't aware there was actually so many. Just to clarify, I am only after calipers for motorcycles, preferably a 4 pot rear caliper.

So far I have managed to find comparible ones from:

Brembo
Harrison Billet
Wilwood
ISR

Currently waiting to hear back from Pretech.

Thanks for the help so far Thumbs Up

Why does it have to be a rear calliper then?

I'd have thought a top of the range 6-pot front calliper mounted on an appropriate bracket would be better.

Remember that the rear brake on sports bikes is something of an irrelevance in many situations because under full braking, the weight is thrown forwards and the back wheel tends to lift off the road. There is little to no grip being derived from it and the brake is correspondingly rubbish.

That's why you'll be finding most bikes have a token-effort single pot rear calliper.

Front callipers are for stopping. Rear callipers are for riding slowly and passing the MOT.

You can also fit TWO callipers on each disc if you want. Check this out:

They use the rear calipers from AP Racing as simply they do what is needed for the formula student tests.

Using a 4 pot rear on each wheel will make the car skid from full acceleration IIRC is one of the tests.

Like this:

As for why those ones?

Compared to an equivalent rear from Brembo with the same diameter pistons:

Brembo

Weight: 267g
Cost: Aprrox £900

AP Racing:

Weight: 500g
Cost £380

Plus, for our Uni, the students have to raise the finance to build the car, so budgets are usually a very governing factor on choice of components.

Nearly finished my first draft of the upright with the AP Racing caliper mounted just to see how it would look so far:

In my experience with brakes, more is more.

Taking my bike (a VFR750) for example. You could lock the front wheel with the standard two pot sliding callipers at well over 100mph. It does however take a lot of pressure, they are a bit wishy-washy. With a lot of weight on at speed, it's all a bit unpredictable and you have to pull hard.

I fitted a set of VTR1000 4-pots. These were much better but still took 4 fingers to haul up in a hurry with some weight on.

The Pretec 6-pots I just fitted to my latest one are a world apart because while you could still lock the wheels just as effectively with the 2-pots, the pretechs give you a lovely linear and progressive action from a little bit of braking to exceeding the traction of the tyres. More of a feeling of moving the lever further than squeezing it harder, you pinch it with your hand rather than pulling it with your forearm muscles.

I'd imagine it would be a similar effect in a car, moving the lever with your foot for a progressive, linear increase in braking force rather than standing on it with your leg to lock the wheels.

Dunno what a forumla studen car weighs but if a motorcycle race team can justify the weight and expense of fitting twin 6-pots to the front wheel of a motorcycle with the tiny little contact patch it has. I'd imagine the more braking you can fit in your student racer with a comparatively massive contact patch and ?more weight?, the better.

Or maybe you have to use 4-pots in the rules?

I wonder how much a set of Yamaha blue-spots weigh?

Had Sumitomo 6 pot calipers on my Exup for years now.The swept area is larger than with the standard 4 pot calipers and I could machine the EBC discs where they are not used - if I could be bothered.

The known modification to FZR1000R and RU models is to fit the one piece calipers from the R1 or similar,but I prefer the 6 pots Thumbs Up
