Product Description
The genuine Toyota 42443-60020 (Rear Backing Plate Paper Gasket / Gasket, Brake D) is a premium quality, precision-cut sealing component designed to seal the critical interface between the rear axle housing and the brake backing plate. Its primary function is to prevent differential gear oil from leaking into the braking system, as well as to stop moisture, dust, and other contaminants from entering the axle assembly.
Technical Characteristics and Material Composition
- Material: Special oil- and heat-resistant impregnated gasket paper featuring excellent compression characteristics and dimensional stability.
- Installation Position: Rear axle, positioned between the axle housing and the brake backing plate.
- Original Equipment Quality (OEM): Genuine Toyota part ensuring a precise fit, exact bolt hole alignment, and long-lasting durability.
- Environmental Resistance: Outstanding resistance to gear lubricants, greases, and operational temperature fluctuations.
Function and Importance
The rear brake backing plate gasket plays a vital role in safe vehicle operation. If the gasket degrades or fails, gear oil from the axle housing can migrate into the brake drum or onto the brake disc. This causes oil contamination of the brake friction linings, drastically diminishing braking efficiency and creating a severe safety hazard.
Typical Signs of Failure
- Visible oil leakage or seepage around the lower section of the rear brake backing plate.
- Sudden or gradual loss of braking efficiency on the rear axle due to oil-contaminated brake pads or shoes.
- A slow drop in differential oil level without evident external case damage.
- Abnormal accumulation of dust, dirt, and road grime inside the brake assembly.
Installation Guidelines
When replacing the gasket, mating metal surfaces must be thoroughly cleaned of old gasket material, corrosion, and grease. Install the gasket dry or with a thin layer of sealant in accordance with factory specifications. Tighten the mounting bolts in a crisscross pattern to the manufacturer-specified torque to ensure even sealing and prevent component distortion.
