Disc brakes are the premier choice for vehicles that require superior stopping power and offer a sleek, race-inspired aesthetic.
The Right Stuff offers a selection of rear disc brake conversion kits to fit most trucks and SUVs. Each kit includes all necessary components for installation as well as some extras to make your job simpler.
Brake Rotors
When Chevy upgraded their pickup trucks’ weight designations from 10/20/30 to 1500, 2500 and 3500 pounds, they needed more stopping power than what the stock drum brakes could provide. As such, they created a big brake conversion kit with new rotors, pads and calipers for use with larger vehicles.
There are a few companies that offer Gmt400 rear disc brake conversion kits. Little Shop MFG provides both 5lug and 6-lug kits for the GMT400, along with Willwood’s 4WD big brake kit. You may also find kits from Summit Racing or Jegs.

Calipers
When it comes to the GMT400 rear disc brake conversion kit, there are a few caliper options. Willwood offers single caliper kits, Cunningham Machine offers a billet aluminum kit and SSBC Brakes offers both 5-lug and 6-lug trucks an appropriate disc brake conversion kit.
Little Shop MFG and StopTech both offer 5-lug truck kits as well. Additionally, you can find many more kits on websites like Summit Racing or Jegs rather than simply doing a Google search.
One of the best upgrades you can do for your GMT400 is replacing its soft, spongy master cylinder with a new body style master cylinder. This relatively inexpensive upgrade will dramatically improve pedal feel and braking performance.
Brake Pads
Upgradeing the brake pads on the front of your GMT400 rear disc brake conversion can be a great way to increase stopping power. Make sure the rotors have the appropriate thickness and pad type for the load you plan on placing on them.
Finding brake pad kits for a GMT400 rear disc brake conversion should be found on the websites of companies that specialize in this product. Some offer full systems with calipers, rotors and pads while others just supply individual pads or rotors. It’s essential to purchase from an established brand with quality products – like StopTech who offer several kits with customizing options available.
Brake Lines
When considering a GMT400 rear disc brake conversion, it’s essential to understand that this requires an entirely different approach than just replacing the factory rotors and pads. Instead of simply replacing those components, you must replace the entire system.
This includes brake calipers, master cylinder and lines – which you can find at most auto parts stores or online. SSBC Brakes offers this kit that fits GMT400 K1500 Fullsize Pickup or 4WD SUVs with stock drum brakes. It contains everything needed to convert them to high performance rotors and calipers as well as a new master cylinder and stainless steel flex hoses for an affordable upgrade that will improve the brakes on your GMT400 and eliminate soft spongy feeling from its original system.
Brake Booster
Brake boosters are devices used to activate the power disc brakes in your GMT400 rear disc brake conversion. They do this by attaching a vacuum pump under your truck or car’s firewall.
A front brake booster is often included in a kit to convert your vehicle from drum brakes to disc brakes. This simplifies installation and improves the performance of your braking system.
A big brake kit is an ideal way to improve your GMC gmt400’s braking performance and add some flair to your truck. There are plenty of places where you can purchase one, but make sure you do some research first.
