Re: Heavy duty brakes

Hello everybody;

I did some Internet research and these are the results. I tried to be exact as possible, but there wasn't that much information out so this is my best try. If somebody can confirm or correct me I would greatly appreciate it.

First of all, there are three sales codes describing the brakes;
- BRY - Standard Anti-Lock Brakes (Front-vented, rear-solid, for 17")
- BR6 - Heavy Duty Anti-Lock Brakes (Front-vented, rear-vented, for 18")
- BR1 - European Anti-Lock Brakes (Front-vented, rear-vented, for 18")

Part list for Front:
Front caliper and brake pads are the same for SD(BRY) and HD(BR6) brakes:
Caliper Assembly (for BRY and BR6):
Right - 68052362AB $156
Left - 68052363AB $156
Brake Pad Kit (for BRY and BR6):
Both - 68052369AA $131 (2x)
Only the adapters for the calipers and the rotors are different:
Adapter Disc Brake Caliper (for BR6):
Both - 68052372AA $22 (2x)
Rotor (for BR6 and BR1):
Both - 68035012AB $105 (2x)
Part list for Rear:
Rear brake pads are the same for SD(BRY), HD(BR6) and Euro (BR1) brakes:
Brake Pad Kit:
Both - 68052386AA $80
These are different:
Caliper Assembly (for BR6 and BR1):
Right - 68052380AA $70
Left - 68052381AA $70
Adapter Disc Brake Caliper (for BR6 and BR1):
Both - 68052374AA $26 (2x)
Rotor (for BR6 and BR1):
Both - 68035022AB $84 (2x)
All together looks like an easy upgrade, with a rough calculation it is about $614 (without pads) and I didn't look for the cheapest provider. Everything despite the parts above remains the same.

Actually the ideal moment for a swap would be when the rotors have to be replaced (the upgrade is about $240 as you have to buy the rotors anyway) .

Big questions remaining are;
1) How much better are the HD brakes?
2) Is there are reprogramming of the system required?

My personnel answers would be;
1) Based on the increased size and the vented rear, the brakes should fade less in towing and down hill
2) As the system is a feedback circle based on sensor input, it shouldn't be necessary.

Looking forward to your comments

BR
Alex
