1989 Geo Tracker: Rear Brake & Exhaust System Overhaul

Rear Brake System Overhaul

• 🛠️ The 1989 Geo Tracker required significant rear brake work, including new brake shoes, wheel cylinders, and all associated hardware.
• ⚠️ The initial assessment revealed a low brake pedal, suggesting a complete failure of the rear brake system, possibly due to a delaminated brake shoe.
• 🔍 Sourcing parts proved challenging, with a need to order aftermarket components from various suppliers, including Rock Auto, due to local unavailability.
• 💡 The process involved replacing a single-hole wheel cylinder on one side and a double-hole cylinder on the other, requiring careful attention to springs and adjusters.
• ⚙️ A unique self-adjuster mechanism was noted, with specific springs (red and blue) needing correct placement for proper function.

Exhaust System Refresh

• 💨 The exhaust system also needed attention, with a new muffler and tailpipe installed.
• 🔧 The repair involved a three-piece exhaust kit and the use of universal hangers, adapted with bolts and double nuts to secure the system.
• 🚧 Modifications were made to existing hangers and the bumper area to ensure a secure fit, as the original factory mounting points were unclear or missing.

Repair Process and Tips

• 🔧 The video details the step-by-step process of disassembling and reassembling the rear drum brakes, including cleaning mounting pads and installing new hardware.
• 💡 A useful tip for keeping brake shoes clean during installation involves taping them off to prevent contamination from brake cleaner.
• ⚠️ Challenges were encountered with certain tools not fitting the brake shoe retaining nails, requiring alternative methods like using pliers.
• 🔧 The importance of proper bleeding of the brake system is highlighted, with multiple pumps needed to remove air from the lines.
• 🚗 The vehicle's overall condition is assessed, noting its age (1989) and some custom modifications, but the brakes were found to be functional after the repair.
