Toyota Proace Rear Brake Caliper Repair Rebuild Kit 45mm (2016 - Present)

Toyota Proace Rear Brake Caliper Repair Rebuild Kit 45mm (2016 - Present)

Engineered specifically for the Toyota Proace and Proace Verso (2016 - Present) new generation commercial and passenger van series, this premium 45mm Rear Brake Caliper Repair Kit is designed to eliminate hydraulic fluid leaks, resolve parking brake binding, and overhaul frozen or sticking caliper mechanisms.

Composed of high-grade, heavy-duty rubber seals and protective dust boots, this rebuild kit restores tight hydraulic pressure under heavy loads, resolves spongy brake pedal issues, and ensures your rear braking system operates with factory-spec efficiency.

Why Should You Rebuild Your Proace Rear Brake Calipers?

Due to heavy commercial duties, high mileage transit, and shared platform design characteristics, the Toyota Proace's rear brake calipers undergo extreme thermal and mechanical stress. Over time, exposure to road debris, mud, and water tears the protective piston dust boots. This allows moisture inside, causing the 45mm large caliper piston to rust, seize, and drag against the brake rotor.

Common symptoms of a failing rear caliper seal include:

• Visible brake fluid leaks around the rear caliper assembly and dropping fluid reservoir levels.

• Rear brakes dragging or sticking even when the handbrake is fully released, causing excessive wheel, rim, and disc heat.

• A spongy or soft brake pedal feel due to pressure loss or air entering the hydraulic lines.

• Excessive brake dust, burning odors, and uneven or premature wear on the rear brake pads.

This 45mm piston diameter seal kit allows you to completely rebuild your existing assembly, bypassing the extreme cost of purchasing a completely new commercial caliper housing.

Key Product Features:

• Precise 45mm Fitment: Designed as an exact direct match for 2016+ Toyota Proace rear disc brake calipers.

• Premium Rubber Elastomers: Superior resilience against heavy brake fluids (DOT 4 / DOT 5.1) and high operating temperatures.

• Comprehensive Component Set: Includes high-quality piston dust boots, internal hydraulic pressure seals, and slider pin boots for a full service.

• Cost-Effective Engineering: Restores maximum braking safety efficiently without discarding the expensive original caliper body.

Installation Tip: During reassembly, always apply a thin layer of specialized high-temperature brake cylinder assembly paste to the new rubber seals and the piston to prevent tearing during insertion. Be sure to perform a full brake fluid bleed after installation is complete.
