The adjustment tips for the car brake pump include the following steps and precautions:
Tool preparation and safety measures: Before adjusting the brake pump, you need to prepare the corresponding tools, such as wrenches, screwdrivers, etc., and ensure that the vehicle is in a safe parking state.
Disc brake pump adjustment:
Check the wear of the brake disc and brake pads: If the wear is excessive, it needs to be replaced in time, otherwise it will affect the braking effect.
Adjust the position of the brake caliper: Use a wrench to loosen the fixing bolts of the caliper, adjust the gap between the caliper and the brake disc appropriately, and then tighten the bolts.
Check the brake oil pipe: Make sure that the brake oil pipe is not leaking or damaged, and replace it in time if necessary.
Drum brake pump adjustment:
Remove the brake drum: Use tools to remove the bolts on the wheel hub and remove the brake drum.
Adjust the gap of the brake shoe: Change the distance between the brake shoe and the brake drum by adjusting the screw to achieve the appropriate gap.
Check the return spring: Make sure the return spring has good elasticity and can make the brake shoe return to its original position in time after the brake is released.
Practical tips:
Adjust gradually: Adjust a small amount each time, test the braking effect, and avoid over-adjustment.
Clean the brake parts: Before adjustment, clean the dust and oil on the brake disc, brake pad, brake drum and other parts to ensure the accuracy of adjustment and braking effect.
Regular inspection and maintenance: It is recommended to check and adjust the brake pump at a certain mileage or time to ensure the reliability of the brake system.
Difference between pneumatic and hydraulic brake pumps:
Pneumatic brake pump: The braking force can be changed by adjusting the air pressure, the structure is simple, and the fault inspection and maintenance are relatively convenient.
Hydraulic brake pump: The structure is complex, the component precision requirements are high, and it is difficult to directly adjust the pressure of the sub-pump. During maintenance, you can clean, grind the piston and replace the sealing ring to restore its function.
