Overview
The Baer Brakes 4301388FR is a Pro Plus front disc brake system for 1960-1987 Chevy and GMC 2WD 1/2 ton trucks, built around a six-piston Fire Red caliper and a 14 inch two-piece rotor. It is a front-axle upgrade for trucks running 2.5 inch drop spindles, and it fits 1960-1986 Chevrolet C10 and GMC 1000 through C1500 trucks, plus several Suburban years.
Baer’s billet aluminum hubs come with premium bearings already packed, so the hub, rotor, caliper and hardware install as one matched assembly. Pads are the popular D0731 type, and the kit targets 5 lug trucks with a 5×5.00 bolt pattern and 1/2-20 wheel studs.
Key features
- Six-piston fixed caliper in Fire Red, manufactured in Phoenix, Arizona
- Two-piece slotted, drilled and zinc-plated 14.0 inch vented rotor with billet aluminum hat
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons designed to reduce uneven pad wear
- Dual dust, weather and pressure seals; the dust and weather seals are T compliant.
- Billet aluminum hubs with premium bearings, Redline synthetic grease and billet dust caps
- Rotors pre-assembled with NAS high grade stainless hardware and stainless braided hoses
Checking pads and rotors over time
Brake pads wear at different rates depending on how a truck is driven. A truck that mostly sees highway miles can go a long time between pad changes, while frequent trail work, towing or mountain grades shorten pad life and heat the rotor faster. Check pad thickness at every wheel service and compare the two pads in each caliper, since uneven wear often points to a sticking slide pin or a caliper piston that is not moving freely.
Two-piece rotors with a separate billet hat rely on their fasteners staying tight, so check the hat bolts after the first few drives on new hardware. Look at the friction surface for heat cracks, scoring or a blue tint, and replace the rotor if it has run below its minimum thickness or shows deep grooves. Slots and drilled holes help shed gas and water, but they do not remove the need for regular inspection.
- Pad thickness checked at each wheel service
- Rotor surface inspected for heat cracks and scoring
- Hat fasteners rechecked after the first few drives
- Slide pins cleaned and lubricated whenever pads are changed
