Overview
The Baer Brakes 4301368GB is a Pro Plus front disc brake kit for 1978-1988 GM G-body vehicles and S10/S15 2WD pickups, with the S10 and S15 Blazer and Jimmy models also covered. The six-piston caliper is Grabber Blue, and the billet hubs come pre-assembled on stock height spindles.
Stock height spindles mean the kit replaces the front brakes without changing the factory spindle height. The 14.0 inch rotors are paired with a 5×4.75 bolt pattern and M12-1.50 x 51.5mm wheel studs.

Caliper and pad fit basics
A fixed six-piston caliper clamps the rotor from both sides with the pistons pushing evenly. Pad choice affects how that caliper performs, so pads should match the caliper and rotor this kit ships with rather than being swapped for a different friction material without checking. Uneven pad wear often traces to a binding slide or a piston that sticks in its bore, so the caliper should be inspected whenever the pads are replaced.
Before a pad change, check the rotor thickness against its minimum specification and look for hot spots or cracks along the friction ring. Brake fluid absorbs moisture over time, so a fluid flush at regular intervals keeps the caliper pistons and seals working as they should. Route the brake hose so it flows freely without kinking, and inspect it for chafing near the frame or suspension.
- Caliper slide pins inspected and lubricated
- Rotor thickness checked against its minimum specification
- Brake fluid replaced on a regular schedule
- Hoses checked for kinks and chafing

Installation notes
The hubs are already assembled on stock height spindles, so the front spindles do not need replacing. The wheel studs are metric M12-1.50 x 51.5mm, so match wheel hardware to that thread. Check the Q082P template against the 18 inch minimum wheel diameter before mounting wheels. Support the vehicle on stands before working at the front axle.
What’s included
The kit includes Grabber Blue six-piston front calipers, 14.0 inch rotors with stainless hardware, billet aluminum hubs on stock height spindles, mounting brackets, stainless braided hoses and hardware.
