What to Do If the Brake Pump Leaks Oil?

1 Answers

The solutions for a leaking brake pump are: 1. Replace the brake pump oil pipe; 2. Clean impurities or replace the sealing ring; 3. Reinstall the brake pump screws. The brake pump is an indispensable chassis braking component of the braking system. Its main function is to push the brake pads, which then rub against the brake drum to slow down or stop the vehicle. When the brake pedal is pressed, the master cylinder generates thrust to pressurize the hydraulic oil to the wheel cylinders. The pistons inside the wheel cylinders move under hydraulic pressure, pushing the brake pads. The reasons for brake pump damage are: 1. Dirty brake oil causing wear on the wheel cylinders; 2. Aging and wear of the brake wheel cylinder rubber cups; 3. Poor sealing.

How many liters of engine oil are needed for an Octavia oil change?

The Octavia requires approximately 4L of engine oil for an oil change. To confirm whether the added oil quantity is sufficient, you can check the oil dipstick after adding the oil. Oil dipstick markings: There are two markings on the oil dipstick: one is the maximum level, and the other is the minimum level. The normal oil level should not be above the maximum marking nor below the minimum marking. The oil level should be between these two markings. Method for checking the oil level: After adding the oil, start the vehicle and then turn it off. Wait for 3 minutes before checking the oil level. This is because when changing the oil, the oil filter also needs to be replaced. The new oil filter initially contains no oil, and after starting the vehicle, oil will flow into the filter. Waiting for 3 minutes allows the oil to settle back into the oil pan, ensuring a more accurate reading. Remember not to check the oil level on a slope, as the vehicle's tilt will cause the oil in the pan to tilt as well, leading to an inaccurate measurement.
