Overview
The Baer Brakes Track4 front brake kit, part number 4301406HO, is a front disc brake system for 1978-1988 GM G-Body vehicles and 1982-2003 Chevrolet S10 and GMC S15 models, including Blazer and Jimmy versions. It pairs a 4-piston T4 caliper with a 13 inch one-piece slotted, drilled, zinc plated rotor and billet aluminum hubs that come assembled on stock height spindles.
The T4 caliper is made in Phoenix, Arizona, and uses stainless steel pistons with dual dust, weather and pressure seals. The 13 inch Track4 is designed for most 17 inch or larger wheels, so compare the Q082H template with your wheel before installing, since fit cannot be assured with every wheel style.
Key features
- Two-piece 4-piston T4 caliper with a powder coated finish
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons to minimize uneven pad wear
- Dual seals for dust, weather and pressure
- One-piece slotted, drilled, zinc plated rotor
- CNC machined caliper components from US sourced forged or billet aluminum
- Billet aluminum hubs with premium bearings packed with Redline synthetic grease and billet dust caps
- Stainless braided hoses, mounting brackets and hardware included
Hose routing and installation
Braided hoses carry pressure from the master cylinder to the caliper, so their routing matters as much as their fit. A hose that twists, rubs a control arm or sits against a hot exhaust component can fail early. Set the hose length so it has slack through the full range of suspension travel and steering movement, without pulling tight at any point.
After the hoses and calipers are mounted, bleed the system fully and check the pedal feel before driving. Air in the lines causes a soft pedal that can be mistaken for worn pads. Inspect the hose fittings for seepage after the first few stops and again after the first longer drive.
- Route hoses clear of control arms and steering parts
- Bleed the full system after mounting
- Check fittings for seepage after the first drive
