U Jelly ? (VT Accalim with 330mm rotors & Corvette C5 Calipers)

[Tsunamix]

Tips for new users - when mounting PBR2 C5 Corvette rotors, mount them with the Bleed nipple on the top.

Failure to do so will result in aching arms, legs and much swearing, losss of sleep and brake fluid everywhere.

What happens is with the blled nipple facing downwards, a pocket of air is trapped in the back of the top Piston, giving you a totally wallabyted brake pedal.

Thankfully they are a quick relase calliper - one bolt removes and then I could swap sides. And re bleed. and test and check again. Bloody jacks and hand removing wheels..

Sexah stuff you can't see - Kit comes with Braideds Steel brake lines and new ZP line brackets. Also polyurethane hose bushes and new line bracket clamp clips.

Result: brake pedal is high and firm. Response is very strongly linear, making it very easy to adjust brake pedal input to braking requirements. The absolute stopping power is Huge. My eyeballs left indents on the dashboard behind the steering wheel, and it will take a hydraulic jack to pull all the teeth out of my steering wheel.

And they look absolute horn.

The wheels are 17" CSA Gladiators, so they kit will fit any 17" or larger wheel.

Yes - the rotors are powdercoated Red and Marked PBR2 - but with a different logo they are sold to GM USA for the corvette.

The rotors are RDA Gold Series. And that's paint, not gold passivating.

Looks good man, glad it's turned out well!

Those brakes are probably worth more than a vt acclaim itself

[gslrallysport]

I gotta admit I was a little nervous about the clearance! Glad it all worked!

For everyone else I'll have pricing for the other two remaining kits up in my section soon!

i would imagine the 322mm VE rotors and 4 pistons would be close and cheaper... but obviously not corvette spec

That goes for any brake caliper with a bleed nipple on it on any car.

I thought the VE calipers were 2 spot.

(goes and checks)

Yep 2 spot, and the rotors aren't drilled, just dimpled. Also the PBR caliper surface area is much larger, and it's sexah red powercoated. ALso comes with super sexah braided steel lines. Greg charged me like a wounded Ted Bullpit though :P

Actually I reckon it's good value. Dearer than the VE but looks horn, and performs better (thats my guess coz i haven't driven a VT with VE kit, but I have driven a VE and the brakes aren't bad, but they are not spectacular either).

How much is it for replacement disks and pads?

[GlenM]

How many pistons on those calipers?

[TrikkBen]

Is the car really that fast... lol

They do look neat though, good job.

How many pistons on those calipers?

They are twins mate, anytime a caliper that you can see the half circle cutout means that the piston is on the other side of the caliper, two cutouts like the calipers in the picture means twin piston.
They will be the same as the calipers on your car, just bigger (which means more brake pad area) and there made to have 330mm rotors go between them.
So overall better stopping power.

To the OP nice setup by the way.

In answer to a couple of PM's -

The standard brake package on the car is also a 2 piston, but the relationship between the quickfill master cylinder and the standard caliper emant that brake pedal respons was non linear. When you pushed the brake pesal, and held it still, the rate at which the car de-celerated would vary.

The pedal response with the PBR2 caliper is linear. So you can modulate your braking more smoothly, accuratley and with greater confidence.

The performance is awesome, no doubt. And they will be fine for the occasional track day as well.

Unlike many people, I firmly believe in replacing ordinary stuff, with the best I can afford, when it comes time to replace. I had worn the previous slotted rotors out - a hard spot in the pads had grooved the rotor quote badly, and was up for 900 odd dollars to fit the new VE kit. This seemed better again, certainly better looking. So I stumped up.

There's also alot less flex in this caliper too versus the VT-VZ or VE...
PBR C5 > VE > VT-VZ

Another advantage of this kit (versus the VE kit) is that the rotors are off the shelf parts, not modified to suit like the [14mm stud] VE rotors.
