Overview
The Baer Brakes 4261558S is an 11.9 inch front Pro Plus brake system in silver, sold as a kit for the 1976–1977 Ford Bronco. It pairs a six-piston (6P) caliper with a two-piece rotor, aimed at owners who want a front disc upgrade on a stock disc spindle, with the vehicles covered listed in the fitment section below.
The two-piece rotor arrives pre-assembled. Its 6061 T-6 billet aluminum hat is fastened to the friction ring with high grade NAS (aircraft) hardware. The silver caliper has a powder coat finish, and custom colors and finishes are available on request.
Key features
- Six-piston, two-piece caliper with six 3/8in. cross bolts for added strength.
- Stainless steel pistons, abutments and noise suppression springs.
- Staggered piston sizes intended to minimize pad wear.
- Dual seals for dust, weather and pressure.
- Two-piece rotor with a 6061 T-6 billet aluminum hat and high grade NAS (Aircraft) hardware.
- Caliper can accept 13in and 14in rotors.
- Uses the C5 and C6 backing plate (1997–2013 Corvette) or the Fmsi D733.
- Uses banjo style fittings; Baer does not use any pipe thread.
Caliper and pad pairing
A six-piston caliper spreads clamping force across more pistons, so pad choice matters. Pad compound should suit the heat your driving creates, from street stops to steep trail descents. Mismatched pads can glaze or fade, and the staggered pistons on this design are meant to help with even pad wear when the pads are the right fit.
Changing to a larger braking system often means checking the master cylinder, reservoir and fluid. A bigger caliper moves more fluid, so confirm the existing hydraulics can supply it. Bleed the system fully after installation, and test the pedal at low speed before taking the truck on a trail.
- Replace banjo crush washers at every joint
- Use fresh brake fluid when bleeding
- Re-check fittings for seepage after the first drive

Vehicle fitment
It fits the 1976–1977 Ford Bronco in Custom and Sport trims, and it is made for stock disc spindles only.
Other Ford trucks, later Bronco generations, and Bronco models outside the Custom and Sport trims fall outside this fit. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Brake hoses are not included, and the caliper uses banjo style fittings, so any hoses you add must be matched to those fittings. The product note calls for a stock disc spindle, so check the spindle before starting the install. Brake work directly affects stopping, so have a qualified installer fit and test the system.
