The brake system is hydraulic, two-circuit, with a diagonal separation of circuits. One hydraulic circuit provides the right front and left rear brakes, the other - the left front and right rear. This greatly improves the safety of the vehicle. If one of the circuits fails, braking is performed by another circuit. When you press the brake pedal in the main dual brake cylinder, the pressure of the brake fluid acting in both circuits arises. A pressure distributor connected in series with the master brake cylinder ensures that the rear wheels do not lock up during heavy braking. COROLLA COMBI for this purpose has an additional 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 brake master cylinder and provides fluid to the entire system.
The vacuum booster uses part of the vacuum created in the engine intake tract. The vacuum booster reduces the required force applied to the brake pedal. Therefore, the diesel engine has a special vacuum pump located behind the generator for this purpose. The vacuum pump is driven by a camshaft belt.
Disc brakes have a floating caliper that presses the brake pads against the brake disc with a single piston.
Parking (manual) the brake has a mechanical drive acting on the drums of the rear wheels.
Brake pads for disc brakes, as well as brake pads for rear drum brakes, are self-aligning. Their adjustment is required only after repair and if the entire brake system was disassembled.
When cleaning the brake system, brake dust is generated. This dust is harmful to health. It should not be inhaled.
It is recommended to use original TOYOTA pads.
Special cleanliness must be observed when working on the brake system. In the absence of experience in working with the brake system, you should contact a specialized workshop.
Note When driving on wet roads, it is recommended to apply the brakes periodically to dry the rims. Water due to centrifugal forces is discharged from the brake discs, leaving a thin film of silicone, a product of rubber wear, grease and contamination that reduce the effectiveness of disc brakes.
After installing new brake linings, they should run in. Therefore, the first 200 km do not produce sudden braking.
