MOT No. 16
To carry out the inspection, the lower part of the body must be dry so that you can see leaks. Moisture-dark spots suggest a leak.
Check all connections, as well as disc brake calipers and drum brake shields, behind which the wheel brake cylinders are located.
Brake hoses must not be wet, swollen or frayed. Otherwise, they must be replaced.
The pipelines of the brake system have an anti-corrosion coating. If this protective layer is damaged, rust formation may begin. Therefore, you should never clean serviceable brake lines with a screwdriver, emery cloth or wire brush.
If the protective layer is damaged, an anti-corrosion primer should be applied in a thin layer.
Tubes with traces of rust or crushed must be replaced.
Are all bleed valves protected by protective caps? They are located on the disc brake calipers or inside the drum brake guards.
You can do an impromptu brake pressure test yourself:
Depress the brake pedal with full force.
It should not give in even after several minutes of full load, otherwise one of the cuffs of the main brake cylinder is defective.
Due to a leaky cuff, the fluid level in the reservoir does not decrease, however, the squeezed fluid flows through the piston in the brake master cylinder to the other side, where there is no pressure.
Leaky places on the cuffs of the pistons of the disc brake calipers and drum brake cylinders can be recognized by dark places on the disc brake calipers or drum brake shields.
If you are not sure, contact the workshop.
