Re: Laredo X Guys - HD brake upgrade from STD?

I thought I would bring this thread back and ask someone if they understand the whole 6500 vs 6800GVW and the HD brakes. Im confused as to the brake difference as they both have the same towing and payload capacities.

Re: Laredo X Guys - HD brake upgrade from STD?

They have the same towing, but 300 lbs less cargo/passenger payload weight. The pads are the same but the calipers and rotors are different on HD allowing better cooling and braking distance.

Here is a better explanation of the difference between Standard and HD brakes.


Standard brakes:
require 17" minimum for brake clearance

330mm diameter rotors
Vented front rotors
Solid rear rotors

Heavy Duty/European Anti-lock brakes
require 18" minimum for brake clearance

350mm diameter rotors
Vented front rotors
Vented rear rotor

The improved feel of the HD brakes come from the increase in size yeilding more mechanical leverage.

The additional size also aids in cooling since there is more surface area also with the rear vented rotors.

Since the calipers are basically the same the improvement comes from increased everge and not any increase in clamping force.

Re: Laredo X Guys - HD brake upgrade from STD?

My OE brakes where great, I did the fronts only, rears are soon. It's all subjective and butt dynoish, new pads vs. old... During regular use I found them invisible, at first I used retail store top shelf for pads and rotors and can say the initial bite did feel stronger, barely but better. My favorite difference was more leverage than I thought I'd feel above 65 and the improved lack of fade with harder use. Adding an aggressive pad, lines, and a gooder rotors makes a 2/3 again difference. I would recommend this with everyone's first brake job.

Thanks for your response. So you're saying its good first step upgrade to get the larger fronts... with the main benefit of the upgrade being fade resistance at speed and high use vs. initial bite.

Re: Laredo X Guys - HD brake upgrade from STD?

Just the fronts will make you feel more comfortable with the brakes, we're talking a minor, fairly small, but very nice amount. Yes the upgrade is worth doing on its own, in reality any perceived gain in feel is going to come from the front upgrade. The rears will contribute more in the name of fade resistance and enduring use, think downhill with a trailer, logic, so it's not truly of any benefit around town, sorta, but it's also a great upgrade. Together the braking system feels better suited to the jeep. It's worth every cent. Next is brembo, but I don't want to give up my 18's yet.

Re: Laredo X Guys - HD brake upgrade from STD?

With the HD brakes only the front rotor diameter is larger.

HD front rotor: 350mm
SD FRONT ROTOR: 330

HD rear : 330
AS rear :330


So doing the front upgrade alone with yield an improvement.
