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.

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.
