Brake System

Watch the Video

Brake Fluid:

This hydraulic fluid distributes pressure via the master cylinder to the wheels. Contact your Service Advisor for appropriate brake fluid service intervals for your Toyota vehicle.

1. Master Cylinder:

Changes the force applied to the brake pedal into hydraulic force.

2. Brake Booster:

Increases the force applied to the brake master cylinder in response to the driver's pressure on the brake pedal.

3. Drum Brake:

When the brakes are applied, the brake shoes press against the drums and slow the rotation of the rear wheels.

4. Disc Brake:

When the brakes are applied, the caliper clamps the brake pads against both sides of the rotor, which slows the rotation of the front wheels.

Air Conditioning System

Condenser:

The high-temperature, high-pressure refrigerant from the compressor passes through the condenser, where it is cooled and changes from a gas to a liquid..

Compressor:

It compresses the refrigerant, and sends it to the condenser under high pressure.

Cooling Unit:

Includes evaporator, expansion valve and thermistor.

Expansion Valve:

Atomizes liquefied refrigerant and injects it into the evaporator.

Receiver:

The refrigerant liquefies in the condenser and is stored in this tank for supply to the evaporator. On newer Toyota models the receiver is integrated into the condenser.
