What's the reason for hard brakes that don't stop the car?
1 Answers
There are many factors that can cause hard brakes that don't stop the car: worn brake pads, air in the brake fluid, deteriorated brake fluid, brake fluid pipe leakage, stuck brake calipers not returning to position, worn master cylinder cup and leaking joints, or malfunctioning ABS pump. Since hydraulic brakes are used, when the engine is turned off, the hydraulic pump that drives the hydraulic brakes stops working, causing a sharp increase in brake damping, which is reflected on the pedal as it becomes very heavy and hard. The following are the standards for replacing brake pads: 1. Thickness: The normal thickness of brake pads is about 10mm, and they should be replaced if it is below 6mm. 2. Sound: If the car frequently makes abnormal noises when braking, it indicates that the brake pads are severely worn and should be replaced. 3. Pedal feel: When the brake pads are severely worn, their braking force decreases, so when you step on the brake, it will show symptoms of weakness, and the brake pads should be replaced promptly.
