Heavy duty brakes
 
Does anyone know what the exact differences are between the "heavy duty brakes" on the hemi w/towing package and "regular" brakes?

Larger front calipers on all hemis, don't think towing package adds anything else to the brakes.

My CRD came with heavy duty breaks as well, i think all the export CRDs do. The front rotors are also bigger by a fair bit. Regular brakes you can fit 17" rims over, heavy duty need to be at least 18" rims and the brakes fill almost the entire rim.

So bigger calipers, bigger rotors

The rear rotors are also ventilated like the fronts.

Which probably means different rear calipers also to accommodate the thickness of the vented rotors, right? Vented are typically at least 2x the thickness of non vented is I would assume you would need a different casting or a really long piston range.

Hi,

Would be interesting if you can easily swap the standard brakes to HD breaks?

New calipers, rotors and pads should be all then? Couldn't be that expensive and difficult. Question would be is it worth it?

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.:o

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 :)

Thanks Alex!

Honestly if you're going to upgrade your "brakes" not breaks, go aftermarket instead if you're going through all the trouble.

Ok,

But i guess they are way more then $600 (did some Internet research and the parts are ~$400 at the cheapest dealer), aren't they?

Question remains for both, is it worth the effort? :confused:Especially looking at the other thread talking about the Brembos? http://www.jeepgarage.org/f109/wk2-srt-brembo-brake-kit-on-an-overland-25604.html

I would think that the standard brakes required certain improvement, while the HD brakes might be sufficient, because for Germany HD is standard for all models and you can run the car 200+ km/h if you want. Not that I would like to start a discussion about that again:D
