Baer brakes, Brembo (c6) or PBR (mustang) calipers. Experinces?

[Ripped]

I was looking at the baer disc conversions. They have the standard kits which use the PBR calipers and an upgrade kit which uses the corvette style caliper.

The corvette caliper is obviously bigger & better, but another factor to consider is that most of us (me included) will be using manual brakes.
I am concerned about how well a manual master cylinder will work with these two types of calipers?

Have any of you done the c5-6 caliper? How does the braking compare to the PBR type?

I am not too far away from deciding on this.

Obviously this is going to be a huge improvement over factory (late 60's) brakes, but this is also a pro-touring type car. It should have REALLY good brakes ;)

I currently have PBR brakes on my 69 (the track plus with 13" rotors fron and rear) I have raced at both Buttonwillow and Willow Springs, my car goes 165 plus on the long straights at both and they work fine for me. I did buy the caliper upgrade kit (6P), I have not put them on yet, but I am sure they will work a little better, by how much better I do not know. I bought the 6P's more for looks, either will be a night and day difference between the stock brakes...

c5 and c6 calipers are also made by PBR, as are the C6ZO6 calipers.

The force applied to the rotor by a caliper is a function of the piston area. Calipers with larger piston areas will provide more force to the rotor. A larger rotor will give a longer lever arm for the caliper to act on, thus also improving braking performance. The ultimate limiting factor in most braking systems are the tires.

With all that being said, you can't go too wrong with a C5 or C6 based system. Use a 15/16" manual MC and you should be good to go with a pedal ratio of 6:1.

Thanks guys, that is really helpful information.

The next question would be rear rotors, I can go 11.75 or 13". It's quite a bit more $ to go to the bigger rears.

Is it worth it, in your experience doing courses etc?

I could, for instance, go with the stock rears and brembo style front calipers, or go to PBR's (mustang GT calipers) and bigger rotors (same basic caliper as the 11.75's). The budget for each will be about the same.

Whatever you choose in the front needs to be balanced in the rear. You really need to know your weight distribution.

I can tell you this. After installing my LSx engine, which dropped 300 pounds of the nose of the car, I can definitely use more rear brake. If I was a betting man, I would say that 11.75 in the rear is good.

Are PBR calipers chinese?? Not trying to drum up any bashing. I was looking into using them and couldnt find much info. Other than the fact they are widely used. JR

PBR is Australian.

PBR is Australian.

X2...made down under, although they have facilities in other countries as well, like most major Tier 1 auto industry suppliers. Check out their website for all of the corporate info: http://www.pbr.com.au/

I have confirmed in the past that all of the C5/C6 calipers are made in Australia along with most (if not all) of their "Slimline" aluminum calipers. Same for the C6 Z06 monoblocks as well. I didn't ask about the Mustang calipers in particular, but imagine they are similar.

Got it.. Thats what I have read and forgot, they are an Ausi company and do contract out some of their work to asia. That sparks my memory. Umm, great calipers either way, they are on SO many cars. Thanks guys. JR

Not trying to jack the thread, but If american made products is a major priority for you JRouche. Check out Performance friction.

Good link. But no, I didnt mean to go on the american made band wagon. There are some great parts manufactured from many countries. Still waiting for india to step up??

I was just interested in where PBR was stationed, I didnt know the company. But had a slim idea, it was an Auzzy based company and they contracted out to china (and others) for some castings. And Im not a fan of chinese casted products simply for quality control. I see too many contractors giving up quality control for profit margins.

Chinese products come in several stages of quality. Its whatever the buyer wants to pay. I have no doubt the chinese can produce supper accurate parts with a focus on quality. So it comes down to the customer and the contract. Ask and you will receive seems to be the line of business. Ask for a certain price spread and you get the melt we give you. Specify a certain melt and they will price it accordingly.

I love that market you get over there. Its all about what you want to pay. You want a certain melt (the alloy) then no problem, ups the cost though. You want a certain tolerance on the as cast part, no problem, increase the cost. You want a lower cost part? No problem, it can be had anyway you want it over there.

If you ever go shopping in china as a manufacture its great, its ale cart. Where do you want your margin. Bottom line. And really, business is business.

You, as a manufacture can get whatever quality you desire. And lemme say, if yer on the high side of quality they really take it serious. In a big way. If yer paying the big bucks for quality then its like the page turns and you get some dedicated folks. Like their life is on the line. Hmmm, dunno why they take it that seriously LOL Its a short walk to the closest wall, and bullets are cheap.

But really, I wasnt on a who makes the best parts type deal. Or bashing china or any other country. I was just trying to wrap up what I thought was the manufacturing process with PBR for my own knowledge. THANKS!! JR
