Overview
The Baer Brakes 4301542B is a black-caliper, 6-piston front disc brake kit with a 13 inch 2-piece rotor, built for the Chevrolet K5 Blazer 4WD. Its front-axle design suits trucks that already have a factory front axle and disc brakes, and the kit is labeled for wheels 17 inch and larger. The caliper is manufactured in Phoenix, Az.
The fitment covers the 1971 to 1974 Chevrolet Blazer, the 1975 to 1986 Chevrolet K10, the 1975 to 1986 K5 Blazer in Cheyenne and Custom Deluxe trim, and the 1971 to 1987 GMC Jimmy. Wheel styles vary too widely to guarantee fit into any one wheel, so compare the Q082H template against the wheel before committing to a build.
Key features
- Black powder-coated 6-piston caliper in a 2-piece design
- CNC machined body from US-sourced forged or billet aluminum
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons for more even pad wear
- Dual seals keep out dust and weather and hold pressure
- 2-piece slotted, drilled, zinc-plate rotor with billet aluminum hat
Caliper finish and upkeep
A powder-coated caliper holds up well when kept clean. Road salt, brake dust and grit can build up around the caliper body and the slide surfaces, so rinsing the assembly periodically helps keep the finish intact. Avoid harsh abrasives on the coating, since scratches can allow corrosion to start underneath.
Because the rotor and caliper work as one system, inspect both during routine service. Look for scoring on the rotor face, uneven pad wear and any sign of fluid seepage at the seals. Dust boots and seals that are cracked should be replaced before they let moisture reach the pistons.
- Rinse off road salt and grit after wet or winter driving
- Avoid abrasive cleaners on the powder coat
- Check seals and dust boots during pad changes
- Inspect the rotor face for deep scoring

It fits the 1971 to 1974 Chevrolet Blazer, the 1975 to 1986 Chevrolet K10, the 1975 to 1986 Chevrolet K5 Blazer and the 1971 to 1987 GMC Jimmy. Fit for the Chevrolet Suburban is unconfirmed, so confirm your vehicle’s year, model and trim before ordering.
Models and years outside those four entries, including the Suburban, are not covered by the list. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Check clearance first by comparing the Q082H template with the wheel you plan to use. Disc brake installation calls for hands-on experience, and the wheel should be checked for clearance before the first drive.
What’s included
The kit comes as one box (box count 1) and includes the black 6-piston 6P caliper plus the 2-piece slotted, drilled rotor with billet aluminum hat.
