Dorman Rear Parking Brake Hardware Kit for Lexus & Toyota — HW17393, direct-fit springs, clips & pins

The Dorman HW17393 Rear Parking Brake Hardware Kit is a direct-fit replacement set of rear parking brake components engineered to restore proper handbrake function for specified Lexus and Toyota models.

If your vehicle’s parking brake feels loose, binds, or the rear brakes drag after long service, worn or broken hardware may be the cause. The HW17393 kit supplies the matching clips, springs, pins and retainers needed to rebuild the rear parking brake linkage to original-style operation. Dorman designs these kits to mirror factory fit and alignment so you can replace fatigued pieces without sourcing individual OEM parts.

What exactly is included and why does it matter?

The kit contains the small metal parts that hold the parking brake shoes and cables in correct position: springs, retainers, pins and associated clips. These components control tension, return action, and securement—critical for consistent parking brake engagement and release.

• Replacement springs to restore return force and prevent brake drag
• Pins and retainers that secure shoes to backing plate
• Clips that lock cables and linkage in factory alignment
• All parts matched to original geometry to simplify installation

How do I know if the HW17393 kit fits my car?

Dorman lists compatible years and trims for Lexus and Toyota vehicles—confirming fitment before buying is recommended. Use your vehicle make, model and trim in the site’s garage or fitment tool, or cross-check the year ranges for each model to verify compatibility.

• Compatible with select Lexus GS, IS, RX, SC models across listed years
• Fits many Toyota models including Highlander, Sienna, Supra, RAV4 and Venza in specified years
• Always verify with the vehicle selection tool for exact trim fit
• Designed as a direct replacement for the original hardware configuration

What performance and durability should I expect from this kit?

Components are manufactured from corrosion-resistant metals and shaped to match OEM tolerances so they withstand normal road use and the cyclical stress of parking brake operation. Replacing fatigued parts with this kit restores reliable movement and reduces uneven wear on the brake shoes.

• Durable construction to resist everyday corrosion and fatigue
• Restores correct return action to prevent drag or incomplete release
• Helps prevent premature shoe or drum wear caused by loose hardware
• Backed by Dorman’s product expertise and automotive parts legacy

How difficult is installation and what tools will I need?

Installation is typically a moderate DIY job for someone comfortable removing the rear wheel and brake drum or rotor to access the parking brake assembly. Common hand tools and basic brake spring pliers or a small punch are usually sufficient; refer to vehicle-specific service information for torque and reassembly notes.

• Requires access to rear brake backing plate or drum—vehicle lift or jack stands recommended
• Basic hand tools plus brake spring pliers or punch/hammer for pins
• Follow vehicle service manual for safety and adjustment procedures
• Professional installation available if you prefer not to perform brakes work

Who is this for? The Dorman HW17393 Rear Parking Brake Hardware Kit is aimed at DIY mechanics and professional techs who need a reliable, cost-effective way to rebuild rear parking brake hardware on compatible Lexus and Toyota models. If your parking brake has slack, inconsistent hold, or the shoes no longer sit true, this kit gives you the OEM-style parts required to restore proper operation and extend the life of the rear brake components.
