The brake system is hydraulic, dual-circuit, with diagonal division of the circuits. One hydraulic circuit ensures the operation of the right front and left rear brakes, the other - the left front and right rear. This significantly increases the safety of the vehicle. If one of the circuits fails, braking is performed by the other circuit. When the brake pedal is pressed, brake fluid pressure is generated in the main dual brake cylinder, acting in both circuits. The pressure distributor, connected in series with the main brake cylinder, ensures that the rear wheels do not lock during sharp braking. For this purpose, COROLLA COMBI additionally has a pressure regulator on the rear axle, which regulates the brake fluid pressure depending on the vehicle load.
The brake fluid reservoir is located under the master cylinder and supplies fluid to the entire system.
The vacuum booster uses part of the vacuum created in the engine's intake tract. The vacuum booster reduces the required force applied to the brake pedal. Therefore, the diesel engine has a special vacuum pump for this purpose, located at the rear of the generator. The vacuum pump is driven by the camshaft belt.
Disc brakes have a floating type caliper, which ensures that the brake pads are pressed against the brake disc using one piston.
The parking (hand) brake has a mechanical drive acting on the drums of the rear wheels.

The brake pads of disc brakes, like the brake pads of rear drum brakes, are self-adjusting. Their adjustment is required only after repairs and if the entire brake system has been disassembled.
When cleaning the brake system, brake dust is formed. This dust is harmful to health. Do not inhale it.
It is recommended to use original TOYOTA brake pads.
When working with the brake system, it is necessary to maintain special cleanliness. If you do not have experience in working with the brake system, you should contact specialized workshops.
Note: When driving on a wet road, it is recommended to periodically press the brakes to dry the discs. Water is thrown off the brake discs due to centrifugal forces, leaving behind a thin film of silicone, a product of rubber wear, grease and dirt that reduce the effectiveness of the disc brakes.
After installing new brake pads, they must be worked in. Therefore, do not brake sharply for the first 200 km.
