Possible malfunctions of the brake system, their causes and remedies (Chevrolet Cruze 1 2008-2016: Chassis: Brake system)

Cause of malfunction	Remedy
Increased brake pedal travel
Leakage of brake fluid from working brake cylinders	Replace failed working brake cylinders, Rinse and dry pads, discs and drums
Air in the brake system	Remove air by bleeding the system
Damaged rubber o-rings in the main brake cylinder	Replace cylinder assembly
Damaged rubber hoses hydraulic brakes	Replace hoses and bleed system
Increased brake disc runout (more than 0.03 mm)	Grind or replace the disc if the thickness of the brake front wheel discs less than 22.0 mm, and rear wheels less than 8.0 mm
Insufficient braking performance
Lubrication of linings of pads of brake mechanisms	Rinse and dry pads
Jamming of pistons in working cylinders	Eliminate the causes of jamming, damaged parts replace
Complete wear of brake pads	Replace brake pads
Overheating of the brakes	Stop immediately and let the brakes cool down mechanisms
Use of low quality pads	Use original pads or products from companies specializing in the production of parts for brake systems
Violation of the tightness of one of the circuits (accompanied by brake pedal failure)	Replace damaged parts, bleed the system
Violation of the brake pedal adjustment (free play pedals over 10mm, total pedal travel over 65mm)	Adjust the position of the brake pedal, determine reason for the increase in full stroke and replace the damaged details
Violation of the adjustment of the protrusion of the vacuum rod brake booster	Contact the service to adjust the amplifier
Violations in the operation of the anti-lock braking system (ABS)	Contact the service to check the anti-lock brake system (ABS)
Incomplete release of all wheels
No free play on the brake pedal	Adjust the position of the brake pedal
Increased protrusion of the vacuum brake booster rod	Contact the service to adjust the amplifier
Swelling of the rubber seals of the master cylinder due to the ingress of gasoline, mineral oils, etc.	Flush and bleed the entire hydraulic drive system, replace rubber parts
Jamming of master cylinder pistons	Check and, if necessary, replace the master cylinder
Braking of one wheel when the pedal is released
Breakage or weakening of the coupling springs of the parking shoes brakes	Replace springs
Seizure of the piston in the working cylinder due to housing contamination or corrosion	Replace slave cylinder and bleed system hydraulic brakes
Swelling of the O-rings of the working cylinder due to foreign matter entering the liquid	Replace the working 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 mounting bolts, replace if necessary time parts
Incorrect adjustment of the parking brake system	Adjust the parking brake system
Violations in the operation of the anti-lock braking system (ABS)	Contact the service to check the anti-lock brake systems (ABS)
Skidding or pulling the car to the side when braking
Jamming of the piston of the working cylinder	Check and repair piston stuck in cylinder
Blockage of any tube due to a dent or clogging	Replace or clean tube
Dirty or oily discs, drums and brake pads	Clean the brake parts
Wheel alignment misaligned	Adjust wheel alignment
Different tire pressure	Set the required tire pressure
One of the brake circuits does not work (accompanied by a decrease in braking efficiency)	Replace damaged parts and bleed the system. If this will not lead to the desired result, refer to anti-lock braking system test service brakes (ABS)
Increased effort on the brake pedal when braking
Faulty vacuum booster	Replace amplifier
Damaged hose connecting the vacuum booster and engine inlet pipe, or its fastening is loose	Replace hose
Swelling of rubber cylinder seals due to ingress of gasoline, mineral oils, etc. into the liquid.	Replace cylinders, flush and bleed system
Squeal or vibration of the brakes
Lubrication of friction linings	Clean the pads with a wire brush using warm water with detergent. Eliminate the causes fluid or grease on the brake pads
Worn pads or foreign inclusions in them	Replace pads
Excessive runout or uneven wear (felt by brake pedal vibration) brake disc	Grind or replace the disc if the thickness of the brake front wheel discs less than 22.0 mm, and rear wheels less than 8.0 mm
