Overview
The Baer Brakes Extreme Plus front brake kit, part number 4301525CY in Comp Yellow, is a complete front disc upgrade for GM 1500 trucks and SUVs. It combines a 6S Monoblock caliper with six pistons and a 15.0 Inch vented rotor. It fits Chevrolet Silverado 1500, GMC Sierra 1500, Tahoe, Yukon and Escalade models in the year ranges covered under Vehicle fitment.
The caliper body is machined from U.S.-sourced 2618 aluminum forging and built in Phoenix, Arizona, with a powder-coated Comp Yellow finish. Stainless steel pistons and abutments are paired with noise suppression clips, and the staggered piston layout helps the pads wear evenly. Pads use the D1247 FMSI type.
Key features
- One-piece Monoblock 6S caliper with six pistons
- Comp Yellow powder-coated finish
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons designed to limit uneven pad wear
- Dual seals for dust, weather and pressure
- 2-piece slotted, drilled and zinc-plated rotor with billet aluminum hat
- Rotors arrive pre-assembled with NAS high grade stainless hardware
Keeping the friction side sound
Front brake friction parts do their best work when the pad compound suits the driving. Street use, towing and hard off-road braking each place different heat loads on the pads and rotor, so the pad choice should match how the truck is driven. Pads that run too hot can glaze, while pads that run too cool may not bite as expected until they are warm.
Caliper seals and brake hoses age over time, even when the truck sees little use. Fluid weeping around the piston seals, cracked hose covers or a pad that drags after the pedal is released are all signs that the hydraulic side needs attention. Reused factory hoses should be inspected whenever the pads are changed.
- Match pad compound to street, towing or trail use
- Inspect caliper seals for fluid around the pistons
- Replace hoses that show cracking or bulging

Installation notes
Rotors come pre-assembled with hardware, and the mounting brackets are included, so you will not need to source them separately. Factory hoses are re-used rather than replaced. With a 19.0 Inch minimum wheel diameter, check your wheel against the N077U template before mounting. A qualified brake technician should handle installation and testing, because brake failure is a serious safety risk.
