1959-71 Dodge D100 Front & Rear Performance Disc Brake Conversion for

1957–1971 Dodge D100 Front & Rear Disc Brake Conversion Kit w/ Power Brake Booster

Bring your D100’s brakes into the modern era: 4-wheel disc, power assisted and fully tunable.

Your D100 was built to work, but its factory drum brakes were never meant for today’s traffic. This complete 4-wheel disc brake conversion transforms how your truck stops. It has big drilled-and-slotted rotors at all four corners, large-bore calipers, an OE-style power brake booster and an adjustable proportioning valve so you can dial in the perfect balance. It’s everything you need, front to rear, in one complete kit.

Front disc brakes built to stop a truck

12" drilled & slotted performance rotors
Big 12" rotors give you more leverage and more stopping power than your factory drums ever could. Cross drilling and slotting help shed heat, gas and brake dust, which reduces fade and keeps the pads biting stop after stop, whether you’re cruising empty or hauling a load.

Big-bore piston calipers with D84 pads
Large-bore piston calipers deliver strong clamping force. They come loaded with D84 brake pads, so they’re ready to bolt on and stop.

Complete front hardware
The kit includes all the wheel bearings, seals, dust caps and mounting hardware, plus heavy-duty caliper mounting plates designed for your D100. There’s no hunting for parts and no second trip to the parts store.

Stainless steel braided hoses
Braided stainless steel hoses with 7/16" banjo fittings resist swelling under pressure for a firmer, more responsive pedal. They look sharp under your truck, too.

Power assist with factory-correct looks

OE-style Bendix reproduction power brake booster & master cylinder
The reproduction Bendix-style booster and master cylinder have the classic look your D100 deserves, with the easy pedal feel of modern power brakes. They look right at home under the hood and do the hard work for you on every stop.

Adjustable proportioning valve mounted underneath
An adjustable proportioning valve mounts right under the master cylinder with pre-bent lines for a clean, compact install. This valve lets you precisely tune front-to-rear brake balance for your rear disc setup, so you can set it exactly right for your tires, load and driving style.

Rear disc brakes for your Mopar 8-3/4" rear end

11" drilled & slotted rotors
11" drilled and slotted rotors match the front for consistent performance and a great look behind your wheels.

Calipers loaded with pads
The rear calipers come loaded with pads and ready to install.

Working emergency brake
The rear calipers have a built-in emergency brake provision, and a universal e-brake cable system is included. Your parking brake works just like it should.

Stainless steel braided hoses
Braided stainless hoses come at the rear too, for a firm, consistent pedal at all four wheels.
