Starting at $9.95, AutoBuffy carries 4 drum brake hardware kits from Dynamic Friction for the Plymouth Gtx. A drum brake hardware kit replaces the springs, hold-down pins, adjusters, and clips that keep brake shoes centered and retracting correctly. When these small parts weaken or corrode, shoes drag, wear unevenly, or fail to hold — turning a minor service into a brake failure.
The most important buying decision is matching the kit to your axle position and verifying it includes every hardware piece your specific drum brake configuration requires. Some Plymouth Gtx applications use a self-adjusting mechanism that differs between the driver and passenger side, so confirm whether you need a single-side or full-axle kit. Beyond fitment, consider hardware quality — OE-spec kits use heat-treated springs and plated fasteners that resist the moisture and heat cycling inside a brake drum.
| Option | Best for | What you get |
|---|---|---|
| OE-Replacement Kit (full axle) | Drivers doing a complete rear brake service on both sides at once | Matched springs, hold-down pins, adjusters, and clips for both wheels — ensures balanced braking and saves labor on a second disassembly |
| Single-Side Kit | Replacing hardware on one wheel only after a confirmed failure on that side | All hardware for one drum assembly; lower upfront cost but requires buying two if the opposite side fails soon after |
| Self-Adjuster Repair Kit | Vehicles where the star-wheel adjuster is seized or stripped but other hardware is serviceable | Adjuster screw, pivot nut, and socket only — targeted fix without replacing springs that still have life left |
| Premium / OE-Supplier Kit | High-mileage vehicles, fleet use, or drivers who want longest service life between drum jobs | Heat-treated, zinc-plated or stainless hardware that resists corrosion longer than economy-grade kits; typically includes a more complete assortment of hardware |
Remove one drum at a time and photograph or sketch the spring layout before disassembly — drum brake configurations vary and the photo prevents assembly errors. Install hardware components in the reverse order of removal, seating hold-down pins fully and verifying return springs hook into the correct anchor points on both the shoe and backing plate. After reassembly, adjust the star wheel until light drag is felt when spinning the drum by hand, then bed the brakes with several moderate stops before driving normally.
