SRT8 big brakes

Anyone got experience with these brakes? I've seen numerous Supra's with them on the internet, but there is quite a lack of reviews about these.

A lot seem to use the Jeep Grand Cherokee SRT8 6 piston front and 4 piston rear calipers.

How do these compare to the UK brakes and other BBKs (Brembo, AP etc).

I find this very strange too. By the looks of the conversations on Facebook you'd assume there would be loads of reviews, but I've not seen a single one either.

Glanza_Mike has this setup, but I'm not sure if he's got it working properly yet (think he said there was a lot of pedal travel)

Delboy52 has these fitted to his Supra, might be worth dropping him a pm.

Glanza_mike does have them and seemed to be working pretty well after a few spirited drives

I fitted Delboy's Bimbo's, these front calipers need a minor trim to fit behind 19's" and a major (12mm?) haircut to fit behind 18's", Mike's are 18's".

Note that no two design of wheel will have the same diameter clearance at the back and this dimension will be different from the inside to outside edge. The calipers needed more taking off one side than the other and after testing for heat expansion clearance and with a final fettle in one spot, they clear the wheel evenly by about the thickness of a good coat of paint.

He has done a few hundred miles with them and they're still not bedded in properly yet, but these things will pull your eyes out.

That is, as long as you have remembered that brakes can only be as efficient as the tyres and suspension will allow, using premium tyres, not slammed or running on 19"s and/or have stretched or silly 30 profile tyres/ski's.

Whilst mapping his Suprastick and confirming (test piloting ) that everything else that had been done to it during the past 4-years were at long last all working properly enough too, I must have done a consecutive dozen 120 to 40 to 120 to 40 etc and they were just warming up.

I found the brake pedal to have a light and positive feel and even though used enthusiastically many times, not once did the ABS need to twitch at me.

There's no fear of cooking these Beasties.

The first caliper was a PITA, without a template to work from it took umpteen test fits to fit

With the modified caliper to use as a template, the other side took a quarter of the time

Whilst I have a fag break to clear the aluminium dust from my lungs, Mike pacifies his nail varnish brush fetish

On-side was first done

They certainly tick the trendy box

They are cosy in there

I've got a set of these waiting to go on my car when all the other work is done to it.

They wouldn't fit behind my 18s tho and may need a very minor trim (1-2mm max in 2 spots) to fit behind my new 19s.

Glanza-mike's wheels are 19s and his fitted no problem at all without any trimming, but every wheel design is different.

One thing, the fronts take the same size pads as an R35 GTR, so I've got a set of Chris Wilson GTR pads to put in mine.

Oh and the discs are cheap. Genuine drilled Brembo discs (360mm + 345mm) from Eurocarparts cost me about £245 for all 4 delivered!

Yeah they're great

It was a nice warm afternoon when me and David were mapping the gearbox and had no brake fade after our repeated stop/start antics. They cost a lot less than Supra Bremos even after shipping from US but the ass is all the fettling to get them fitted. Especially if staying with 18" wheels like me.

The look here is wip:

Ive got a complete set for sale ready to bolt on. Already been fitted.

Have they been trimmed n?

I would not trim callipers

Chris, did they clear the CCW CLASSICS without modification?

Have they been trimmed n?

Have you Tried Specsavers?

Have you Tried Specsavers?

Yes

Don't have a set to fit me!

And does anyone have a list of wheels these fit over ?

I've attached the front caliper measurements to give a bit of help in finding if they will fit under a wider range of allow wheels.

Bear in mind this sheet is based on my modified calipers and measurement 'D' may well be different on a brand new caliper set. A lot of material was taken off the outer shoulders which extend further than the center section where the pistons are.

Where did u buy them from?

I imported from America but Parry in this thread has a set for sale

I think they are definitely worth the money, they look amazing and stop very well.

At first i wasn't 100% sold on the brake pedal feel but i've bled them a few more times and now i think it's fine. The Supra never has an amazingly sharp pedal feel from what i've felt in all the cars i've driven. My pedal now is better than when i had my UK specs on but performance is definitely better.

Mike's took 3 attempts to bleed properly too.

Yeah i'd say i did 3 or 4 times, with about 50 - 100 miles of road driving between each one.

I never did work out if the problem was the ABS, or the design of the calipers, or more likely Mike's drive sloping like a V1 launch ramp, either or, bleeding them was a PITA.

Could it be to do with how the callipers are mounted? They sit much further down than stock or off the shelf brake kits.

My redeeming excuse was to lay the blame on Mike's V1 launch ramp drive for upsetting the function of gravity.

It's not that bad. Had a garage do it in the end, whilst it was in the air having something else done. Probably got the last bubble out and charged a days work as the trend goes.

It's not that bad. Had a garage do it in the end, whilst it was in the air on the level having something else done.

Edited for you Mike.

"It's not that bad."

Not only is it a 1 in 5? slope, it's slippery and uneven and to rub it in, it's pink and shiny too, your gay drive only nearly killed us once.

Note that nose up your gay drive, your nipples are way from the top.

Next time you want to bleed, do it nose down your gay drive, that will get your nipples up.
