Do I Have Standard Brakes.

[PSI O6T]

ok ,its a ba mk1 3/04 . calipers are silver in color,disks look smallish ,so im thinking ive got the standard xr6t brakes right ?

question 1) can I put larger disks with the calipers I already have?

2) what size disks would be on the car ?

3) what size disks are the pbr premiums ?

4) what cars had the pbr premiums ?

sorry for all the questions ,its just that the brakes on my car are the worst ive ever had.....

I have a ba with the pbr upgrade and I have 325mm front rotors. I got told you could

Upgrade from factory or all ex cop cars have them...there also twin piston!

If standard brakes you'll have

298mm fronts and 303mm rears

whats the difference between the pbr premium calipers and the standard ones other than color ?

also can I run 325mm fronts with standard calipers ? so many questions,lol

You can buy a bracket kit, and 325 discs off Ebay that let you use your existing caliper. BA GTs had premium PBR. Just fitted some to my 03 XR6T ute.

The pbr are twin piston! And I haven't had a vibration issue even after about 120 passes down the 1/4

There isn't a great gain to be had in upgrading disc size if the contact of the pad to the disc is the same. You'll only gain because the quality of the rotor would be better.

If looking for a cheap upgrade get a front set of FG calipers and discs, as well as rear territory calipers and discs. Won't be too expensive and will be a massive upgrade from what you have now, especially if you use good discs ad pads

I disagree, a larger rotor give you a greater mass to absorb the heat generated by braking, it also gives you a greater leverage ratio @ the wheel hub compared to the smaller rotor. (greater moment of torque if I remember my high school physics correctly)

PBR premiums - BA Gt or were special order. 325 x 32 Front rotor / twin piston - unique caliper and pad ( not sure about the hoses). I can't remeber the rear set-up.

BF Mk2 - 322 x 28 front rotor / twin piston - same caliper as territory. A fair system but nothing special. Rears are a 303 solid rotor with caliper to suit.

In terms of upgrades the BA premiums are reasonably rated by most people. Race Brakes in Sydney sometimes have new kits. Second hand - well, its brakes and the calipers hoses etc are heading to ten years old so think about that if you find some.

Rears - the very common territory offers a ventilated rotor ( 328??) and a different caliper to that of the BF2 - good upgrade and an easy fit IF you get all of the parts and ditch your dust shields.

Territory Turbo runs a unique rotor package - nice but a bit rare.

If the stock system is really sh*t it might just be pads...... funny how some people want these hipo cars and put 30 dollar pads in them and run the discs down to paper-thin.

Okay listen to this guy he knows much more than me!
