The main malfunctions of the brake system (Chassis / Brake system / Ford Escort 4 1986-1990)

CAUSE	ELIMINATION METHOD
Increased brake pedal travel
Leakage of brake fluid from the wheel cylinders of the brake mechanisms, while oil stains are observed on the calipers or brake drums
Brake pad wear and insufficient brake travel	Eliminated by replacing the pads and cleaning the brake mechanism
Failure of one brake circuit, determined by the presence of brake fluid leaks
Automatic brake pad adjuster not working
The working surfaces of the brake discs or drums are heavily soiled, corroded or worn	Brake discs or drums must be thoroughly cleaned or replaced
Insufficient braking performance
Lubrication of brake pads	Eliminated by washing and drying pads
Jamming of pistons in wheel cylinders	Eliminated by disassembling the cylinders and replacing damaged parts or the entire cylinder assembly
Overheating of the brake mechanisms during frequent and prolonged braking	In this case, you must immediately stop and cool the brakes
Damage to the O-rings in the master cylinder	Eliminated by replacing the sealing rings or the cylinder itself
Wrong brake pads are used
Faulty brake booster
Brake pedal sinks and bounces
Air in the brake system or low fluid level in the reservoir	Eliminated by adding fluid and removing air from the brake system
Vapor lock in overheated brake fluid due to too high water content in the brake fluid	Fixed by changing the brake fluid
Incomplete release of all wheels
No free play on the brake pedal	Jamming of the valve of the vacuum booster requires replacement of the vacuum booster
Swelling of the sealing rings of the brake master cylinder	Eliminated by replacing rings
Uneven brake application
Tire pressure uneven	Eliminated by pumping cold tires
Uneven tire wear on the same axle	Eliminated by installing equally worn tires on one axle
Lubrication of brake pads	Eliminated by washing and drying pads
Jamming of pistons in wheel cylinders	Eliminated by disassembling the cylinders and replacing damaged parts or the entire cylinder assembly
Braking one of the wheels when the pedal is released
Breakage or weakening of the return spring of the brake pads of the rear wheel	Fixed by replacing the spring
Piston stuck in wheel cylinder	Repair the wheel cylinder or replace it
Violation of the position of the caliper relative to the brake disc when the mounting bolts are loosened	Eliminated by tightening the bolts
Sliding or pulling the car when braking
Piston stuck in wheel cylinder	Repair the wheel cylinder or replace it
Dirty or oily discs, drums and linings	Eliminated by thorough cleaning of brake parts
Violation of the angles of the front wheels	Eliminated by adjustment
Different tire pressure	Eliminated by pumping cold tires
Squeak or vibration of wheel brakes
Breakage or weakening of the return spring of the brake pads of the rear wheel	Fixed by replacing the spring
Ovality of brake drums	Eliminated by boring or replacing drums
Lubrication of brake pads	Eliminated by washing and drying pads
Pad wear	Complete pad replacement required
Excessive brake disc runout or uneven wear	Eliminated by grinding or replacing the disc
