Overview
The Baer Brakes 4301368MG is a Pro Plus front disc brake kit for 1978-1988 GM G-body vehicles and S10/S15 2WD pickups, along with the S10 and S15 Blazer and Jimmy models, and it carries a Monster Green six-piston caliper. The kit arrives with the billet hubs already mounted on stock height spindles.
Because the spindles are stock height rather than drop spindles, this front brake package fits the factory geometry of these vehicles. The rotor is 14.0 inch with a 1.15 thickness, and the wheel stud pattern is 5×4.75 with M12-1.50 x 51.5mm studs.
Key features
- Six-piston fixed caliper in Monster Green, built in Phoenix, Arizona
- Vented two-piece 14.0 inch rotor, slotted, drilled and zinc plated, with billet aluminum hat
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons and dual dust, weather and pressure seals
- Billet hubs with premium bearings, Redline synthetic grease and billet dust caps
- Stock height spindles included with the hubs
- Rotors pre-assembled with NAS high grade stainless hardware and steel braided DOT approved hoses
Stock height and front geometry
Stock height spindles keep the front end at the ride height and steering geometry the truck was built with. That matters for brakes because the caliper, hose and rotor sit where the factory designed them, so hose routing and wheel clearance stay close to original. Any suspension lift, drop or large tire change moves those relationships and should be checked before the brakes go into regular service.
Owners who plan a lift or lowering should think about the whole front end at once. Steering arm length, control arm angles and brake hose length can all change, and a hose that is too short can bind at full suspension travel. Wheel bearings and ball joints are often inspected while the hubs are off, since the same work exposes them.
- Brake hose length checked after any ride height change
- Ball joints and tie rod ends inspected while hubs are off
- Steering play checked after the first short test drive

Installation notes
The hubs come assembled on stock height spindles, so no separate spindle work is needed, but the wheel studs are metric M12-1.50 x 51.5mm and wheel hardware must match that thread. Check the Q082P template against the 18 inch minimum wheel diameter before mounting a wheel. Support the vehicle securely before removing the front wheels.
What’s included
The kit includes Monster Green six-piston front calipers, 14.0 inch rotors pre-assembled with stainless hardware, billet aluminum hubs on stock height spindles, mounting brackets, stainless braided hoses and hardware.
