Overview
The Baer Brakes Pro Plus 13.0-inch rear kit in Hugger Orange, part number 4302344HO, is built for rear axles with the GM small pattern 10/12 bolt flange, flush mount bearing and a 5×4.75/5×5.00 bolt circle. Verify your vehicle’s year, model and trim before buying.
Hugger Orange powder coat covers the CNC machined caliper body. Six pistons in a fixed 6P caliper squeeze a vented 13.0-inch rear rotor, and the rotor is a two-piece slotted and drilled design with a zinc-plated surface and a billet aluminum hat. The backing plate carries the caliper and a one-piece park brake shoe assembly.
Key features
- Six-piston fixed caliper finished in Hugger Orange
- Stainless steel pistons, abutments and noise suppression clips
- Dual seals for dust, weather and pressure
- Two-piece zinc-plated rotor, slotted and drilled, on a billet aluminum hat
- Integrated backing plate with park brake shoe assembly
- Pad type FMSI D0731
Braided hose and fluid care
Braided hoses carry pressure well, but the outer jacket can hide corrosion at the crimped ends. Inspect fittings for seepage and look for kinks or rubbing against suspension components. Hoses are the part of a brake system that most often shows age, so a visual check at every service is worthwhile.
Brake fluid is the other routine item. Fluid absorbs moisture over time, which lowers its boiling point and can soften pedal feel under heavy use. Refresh the fluid whenever the system is opened, and bleed each caliper in the correct sequence. Avoid spilling fluid on paint, since it strips the finish.
- Check fittings for seepage at each service
- Look for kinks, rubbing and chafing
- Replace fluid when the system is opened
- Bleed in order from the farthest wheel

Vehicle fitment
The kit is built around the GM small pattern 10/12 bolt axle flange with flush mount bearing, so it applies to axles with that layout. It is designed for wheels 17 inch or larger.
Match the flange and bolt pattern to your axle, then verify your vehicle’s year, model and trim before buying.
Installation notes
The backing plate sets the caliper position and carries the park brake shoe assembly, so a flange or bolt pattern mismatch would prevent mounting. This kit does not come with park brake cables. Anyone fitting rear brakes with a park brake should have hands-on brake repair experience.
What’s included
Hugger Orange fixed 6P caliper, two-piece 13.0-inch rotors, a backing plate with one-piece park brake shoe assembly, and braided brake hoses with hardware.
