Possible malfunctions of the brake system, their causes and methods of elimination (Chevrolet Cruze J300)

Cause of malfunction	Method of elimination
Increased brake pedal travel
Brake fluid leaking from the service brakes cylinders	Replace failed wheel brake cylinders, wash and dry the pads, discs and drums
Air in the brake system	Remove air by bleeding the system
The rubber sealing rings in the main are damaged brake cylinder	Replace the cylinder assembly
The rubber hoses of the brake hydraulic drive are damaged	Replace the hoses and bleed the system
Increased brake disc runout (more than 0.03 mm)	Grind or replace the disc if the thickness of the brake the front wheel disks are less than 22.0 mm, and the rear ones are less than 8.0 mm
Insufficient braking efficiency
Oiling of brake pad linings	Wash and dry the pads
Seizure of pistons in working cylinders	Eliminate the causes of jamming, damaged parts replace
Complete wear of brake shoe linings	Replace the brake pads
Overheating of brake mechanisms	Stop immediately and allow the brakes to cool mechanisms
Use of low quality pads	Use original pads or products from companies, specializing in the production of brake system parts
Breach of tightness of one of the circuits (accompanied by a failure of the brake pedal)	Replace damaged parts, bleed the system
Brake pedal adjustment fault (free play pedals more than 10 mm, full pedal travel more than 65 mm)	Adjust the position of the brake pedal, determine cause of increase in full stroke and replace damaged details
Violation of the adjustment of the vacuum rod protrusion brake booster	Contact the service to adjust the amplifier
Malfunction of the anti-lock braking system (ABS)	Contact the service center to check the anti-lock braking system (ABS)
Incomplete release of braking of all wheels
There is no free travel of the brake pedal	Adjust the position of the brake pedal
Increased brake booster rod protrusion	Contact the service to adjust the amplifier
Swelling of the rubber seals of the master cylinder due to gasoline and mineral oils getting into the liquid oils, etc.	Flush and bleed the entire hydraulic system, replace rubber parts
Seizure of master cylinder pistons	Check and replace master cylinder if necessary
Braking one wheel with the pedal released
Fracture or weakening of the parking brake shoe tension springs brakes	Replace the springs
The piston is stuck in the working cylinder due to contamination or corrosion of the housing	Replace the slave cylinder and bleed the system hydraulic brake drive
Swelling of the working cylinder sealing rings due to ingress of foreign impurities into the liquid	Replace the slave cylinder and bleed the hydraulic drive brakes
Violation of the position of the caliper relative to the brake disk when loosening the mounting bolts	Tighten the mounting bolts, replace if necessary time-based details
Incorrect adjustment of the parking brake system	Adjust the parking brake system
Malfunction of the anti-lock braking system (ABS)	Contact the service to check the anti-lock brakes brake systems (ABS)
Skidding or pulling the car to the side when braking
Jamming of the working cylinder piston	Check and eliminate piston sticking in the cylinder
Blockage of any tube due to a dent or clogging	Replace or clean the tube
Contamination or oiling of discs, drums and brake shoe linings	Clean the brake components
Wheel alignment angles are incorrect	Adjust the wheel alignment angles
Different tire pressures	Set the required tire pressure
One of the brake system circuits is not working (accompanied by a decrease in braking efficiency)	Replace damaged parts and bleed the system. If this will not lead to the desired result, please contact anti-lock braking system testing service brakes (ABS)
Increased brake pedal effort when braking
The vacuum booster is faulty	Replace the amplifier
The hose connecting the vacuum booster and the engine intake pipe, or its fastening is loose	Replace the hose
Swelling of rubber cylinder seals due to contact with gasoline, mineral oils, etc.	Replace cylinders, flush and bleed the system
Squeaking or vibration in brakes
Oiling of friction linings	Clean the linings with a wire brush using warm water with detergent. Eliminate the causes liquid or grease getting on the brake pads
Wear of linings or foreign inclusions in them	Replace the pads
Excessive runout or uneven wear (felt by vibration of the brake pedal) brake disc	Grind or replace the disc if the thickness of the brake the front wheel disks are less than 22.0 mm, and the rear ones are less than 8.0 mm
