Toyota Proace Front Brake Caliper Repair Kit (45-48mm) (2013 - 2016)

Toyota Proace Front Brake Caliper Repair Kit (45-48mm) (2013 - 2016)

Designed to restore hydraulic sealing and mechanical function to the front brake calipers of Toyota Proace (2013 - 2016 / 1st Gen / MDX Chassis) vehicles, this Front Brake Caliper Seals & Boots Repair Kit (45-48mm) is manufactured to strict OEM standards.

Under heavy loads and severe driving conditions, caliper rubber seals and dust boots naturally degrade, harden, or tear over time. Damaged boots allow moisture and road debris to enter the caliper bore, leading to fluid leaks, piston corrosion, and binding brakes. Replacing worn seals ensures optimal hydraulic pressure and safe braking efficiency.

Why Is Caliper Repair Kit Replacement Important?

Caliper pressure seals maintain hydraulic pressure while allowing the piston to retract slightly when the brake pedal is released. Protective dust boots prevent water, salt, and dirt from pitting the piston surface. When seals fail, brake fluid leaks out, and corroded pistons lock up inside the housing, causing persistent brake drag, excessive heat, uneven wear, and potential brake failure under heavy payload conditions.

Symptoms of Worn Caliper Seals and Boots

• Brake Fluid Leakage: Wet spots or fluid residue around the front caliper body or inside the wheel rim.

• Brake Drag & Overheating: The caliper piston fails to retract properly, causing constant pad-to-rotor friction, scorching temperatures, and burning odors.

• Soft or Spongy Brake Pedal: Air or fluid loss in the hydraulic lines resulting in loss of pedal firmness.

• Vehicle Pulling to One Side: Unequal braking pressure across the front axle due to a sticking or leaking caliper.

Cost-Effective Solution: Rebuilding the original caliper housing with fresh high-grade rubber seals and dust boots restores factory braking performance without the heavy expense of replacing complete calipers.

Key Product Features

• Precision Fitment: 100% compatible with 45mm - 48mm front brake caliper systems on 2013 - 2016 Toyota Proace I (MDX) models (1.6 D, 2.0 D, etc.).

• Heavy-Duty EPDM Material: Formulated to withstand DOT4 brake fluids, extreme brake heating, and harsh road environmental exposure.

• Protective Dust Boots: Flexible, tear-resistant seals engineered to keep contaminants out of the caliper hydraulic chamber.
