Overview
The Baer Brakes 4301542R is a red 6-piston front disc brake kit with a 13 inch 2-piece rotor for the Chevrolet K5 Blazer 4WD. It suits vehicles with a factory front axle and disc brakes, and it requires wheels of 17 inch and larger. The caliper is manufactured in Phoenix, Az, and the kit is built from US-sourced forged or billet aluminum parts.
Fitment covers the 1971 to 1974 Chevrolet Blazer, the 1975 to 1986 Chevrolet K10, the 1975 to 1986 Chevrolet K5 Blazer in Cheyenne and Custom Deluxe trim, and the 1971 to 1987 GMC Jimmy. Wheel designs differ widely, and Baer cannot guarantee fit into any specific wheel, so compare the Q082H template with the wheel you plan to run.
Key features
- 2-piece, 6-piston 6P caliper, CNC machined from forged or billet aluminum
- Powder-coated red caliper finish
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons designed to minimize uneven pad wear
- Dual seals for dust, weather and pressure
- 2-piece slotted, drilled, zinc-plate rotor with a billet aluminum hat
Before you buy
Big-brake swaps on older GM trucks usually mean the front hub, spindle and wheel offset all need to be checked together. A larger rotor and caliper need more clearance inside the wheel, so the template check is the step that matters most before any parts are fitted. Compare the template with the exact wheel, tire and backspacing you plan to run, and look for contact at the caliper body and the inner wheel face at full steering lock.
Factory front axles on these trucks are often serviced at the same time. Wheel bearings, ball joints and tie rod ends that show play should be replaced before the new kit goes on, so the rotor runs true and the pads wear evenly. Any brake lines that are reused should be checked for cracks and seepage.
- Check wheel backspacing against the caliper body
- Inspect wheel bearings and steering joints for play
- Replace worn pads together with the rotor
- Confirm steering clearance at full lock

Vehicle fitment
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.
Not covered by the list: the Chevrolet Suburban and any model or year outside the four entries above. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Start with the Q082H template: lay it against the wheel you intend to run before the kit is mounted. Brake work should be done by someone experienced with disc brake systems, and wheel clearance should be confirmed before the vehicle is driven.
What’s included
The kit arrives as one box (box count 1) and includes the red 6-piston 6P caliper and the 2-piece slotted, drilled, zinc-plate rotor with its billet aluminum hat.
