Overview
The Baer Brakes 4302575R is a Classic Series rear disc brake conversion kit for 1963–1987 Chevrolet and GMC 2WD C10 trucks and SUVs with an OE 10/12 bolt C-clip rear end. It swaps older rear drums for an 11.65 inch vented rotor, a red floating caliper with an integral park brake, and stainless braided brake hoses.
The kit suits owners of older 2WD pickups and SUVs who want rear disc brakes in a complete package. It is rated for wheels of 15 inch and larger, with a minimum wheel diameter of 15.0 inch. Compare the template to your wheel before mounting, because clearance differs between wheel designs.
Key features
- Single-piston floating caliper with integral park brake, red powder coated
- One-piece vented rotor measuring 11.65 inch outside diameter
- Slotted, drilled and zinc plated rotor face for a finished look
- Stainless braided brake hoses with DOT approved rating
- Ceramic pads matched to the common FMSI D0627 specification
- Complete kit with brackets, hardware and fittings
Working on an older axle
Older C10 rear ends often show age-related wear, including worn axle bearings, leaking seals and corroded brackets. Inspect those parts before the conversion, because a disc setup puts new load on the hub and bearing. Clean and check the axle flange and backing plate mounting surfaces so the new hardware seats flat.
Park brake cables are sold separately, so plan the routing before the caliper is mounted. Older frames may have worn cable guides, so check the path for rust and sharp edges. Once everything is assembled, bleed the system and test the pedal with the truck stationary before driving.
- Replace worn axle seals before the disc conversion
- Check brake line routing for chafing near the frame
- Re-torque caliper bracket fasteners after the first drives

Installation notes
Park brake cables are sold separately, so the integral park brake will not function until cables are supplied. Compare the template to your wheel before mounting, because clearance depends on the wheel design. Brake components affect stopping performance, so have the work reviewed by a qualified technician.
