Overview
The Baer Brakes 4302136MG is an Extreme rear brake system for 1999–2019 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks. It also covers Tahoe, Yukon, Suburban, Yukon XL and Escalade models within the years shown. It combines a 14 inch one-piece monoblock caliper with a slotted, drilled rotor and a Monster Green finish.
The parking brake side is reused from the original vehicle, so the kit suits trucks with factory rear disc brakes and a manual park brake. The 6S caliper is CNC machined from 2618 aluminum forging in Phoenix, Arizona. A floating caliper slides on guide pins to clamp both pads against the rotor, and the monoblock body is one piece rather than a two-piece housing that bolts together.
Key features
- 1-piece monoblock, 6-piston, 6S floating caliper
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons to minimize uneven pad wear
- Dual dust/weather and pressure seals
- 14.0 inch one-piece slotted, drilled, zinc-plated vented rotor with a billet aluminum hat
- Brackets and hardware included
- Powder-coated Monster Green caliper finish
Parking brake and daily use
A monoblock caliper is a single casting, so it has no separate halves to separate or re-torque. Its seals and pistons still need regular attention, though. Pull the wheel and look at the boot condition, pad thickness and the slide pins whenever the tires come off, and clean any built-up dust so the pads move freely.
The parking brake is a separate system, and on a truck with a reused park setup it deserves a quick check after the install. Make sure the lever travels correctly and holds the truck on a slope. Heavy towing and frequent hard stops generate more heat, so keep an eye on pad wear and rotor color during those periods.
- Inspect caliper boots and slide pins each tire rotation
- Check park brake travel after installation
- Watch pad wear when towing

Installation notes
Brackets and hardware come with the kit, while the factory hoses and park brake are reused, so inspect those parts before the new caliper is mounted. Template N228P checks wheel clearance against the 18.0 inch minimum wheel diameter. Brake work is safety-critical, so pump the pedal to seat the pads and test stopping in an empty lot before driving on public roads.
What’s included
The kit includes the 6S monoblock caliper, the 14.0 inch one-piece rotor with a billet aluminum hat, and the brackets and hardware.
Not included: park brake, which is reused from the factory setup.
