ve hsv brakes 6 or 4 pot

[woffty12]

Hi guys can someone help me out ?im looking at buying a set of ve hsv brakes and need to know if the e series hsv range come out with 6 or 4 pot calipers?is the 6 pot an upgrade option?thanks daz

I think (Someone will have to correct me) it was fitted as standard on the GTS's but was an optional extra on the rest of the models. You'll have to be specific in terms of which model/year....

From what understand the ap 6/4 was only an option on the E1 GTS, but options on the E2 & E3 models.

If you go to the HSV Web Site and click on the Spec's tab it will give you all the info you need. All HSV's (VE'S) have 4 pot front and rear the 6 as stated above is an option.

Or, if you click on the "See HSV" Tab , then "HSV Classics", it has all the data for all other models.

How about that... Yeah the GTS SV version has the 6 piston brakes as standard, but optional on the normal GTS.

Thats pretty poor IMO considering the pre-VE GTS has them as a standard equipment.

Maybe HSV should spend a little less time/effort on cosmetics and a little more on a better driveline as standard like they used to do :hide:

LOL are you that ignorant that you think that more pistons make the brakes better???? Maybe you need some china 12 potters!!!

Ignorant? Having had both 4 and 6 piston AP brakes on my VX track car, i can tell you there is a big difference between each set. Not only do the extra 2 pistons help, but they also come with a bigger rotor.

Now i know that the 4 piston set on the VEs are almost as good as the older 6 piston set, but the VE's tend to be a lot heavier to the VT-VZ range so that benefit is offset.

I ask you, have you ever driven a car with both 4 and 6 piston AP brakes? While i agree its not just about the number of pistons, in this case it does make a big difference (AP 4 piston vs AP 6 piston). About the only better brake system ive found/experienced than the AP 6 piston kit is the Alcon Supercar brakes. But at like $12k for a front/rear set their really only for track/race cars.

A couple of questions from someone who is ignorant :

POTs = brake pistons? What does POT stand for?

I've just bought some uprated rotors and calipers. The 4 POT calipers are 2 pistons per caliper (2x pistons * 2x calipers = 4pot?) Or is it 4 pistons per caliper?

Cheers for the info :)

POTS are just terminology for pistons. If you have two pistons per calliper its a 2 pot setup.. Or perhaps I have 20 POT brakes on my car FDC.

From what i understand 4 pots is 2 pistons either side of 1 caliper=4 pots...

If thats the case, how do they fit 6 POTS onto a single caliper? The caliper must be enormous.

i would have a look at a few brake companys that make calipers size varies pitson size varies to put it into perspective the landcruisers come std with 4 pot calipers but they have 5 different piston sizes calipers are all about the same size but

6 piston is 3 pistons each side of a brake disk, ie 6 pistons per caliper.

Yep, to give you an idea here are a couple of pics of a standard 2 piston caliper/brake setup and a AP 6 piston setup. Both are with 18" VY SS wheels. (Sorry about the quality)

To give you an idea, the AP caliper is about 30cm long and 14cm wide. They are physically heavy as well.

Even with hot semi slicks on a race track (Eg lots of grip) if i jump on the brakes at at 200kp/h i get ABS kicking in on all 4 wheels.

The biggest advantage to bigger rotors/brakes, is they resist fade. 3 or 4 hard braking applications and a standard set would start fading badly. After 10-15 heavy applications and they virtually wouldn't work at all. Ive done a lot of work to my car, but the modification i enjoy most (both on the road and track) is the brakes. You cant begin to imagine how good they are...

Seems a pretty popular theory when it comes to engines amongst some enthusiasts...:hide:

VE 4 piston front brakes have pretty impressive stopping power. It would take a serious reason to "need" the 6 piston versions, as opposed to good old simple w@nk factor eye candy.

All this talk of POTS is making me even more thirsty........:beer:

Is there a way of telling the difference between vz hsv ap calipers and ve hsv ap calipers ?also will the vz brakes fit the ve,are the rotors the same size?cheers

nah wont fit they have diff calipers and rotors in every way apart from them both being ap

not sre if this has been discussed before or not, but, how often do the discs need machining/replacing on the VE HSV's

Does 6 pot callipers make them wear out quicker or is it all about the pad compound?

And is the compound different from 4 to 6 piston versions?

thanks :D

anyone?:confused:

It all depends on how you drive the car and also what pad compound you have.You can't determine how long brake pads will last on a car especially when cars and drivers are different.
