Brake System Technology
Brakes apply too quickly, even with light brake pedal application
Grabbing brakes
Prevents wheel lockup during hard/emergency braking
ABS system
A yellow indicator on the dash which alerts the driver to an ABS malfunction.
ABS warning light
Fluid is used to transfer power and motion from the brake pedal to the wheel cylinders and brakes.
Hydraulic brakes
vibration felt in pedal and steering wheel when braking
warped rotors.
Cause the vehicle to veer to the right or left when the brakes are applied.
Pulling brakes
Magnetic generaters or sensors for detecting the rotating speed of each tire and wheel assembly.
wheel speed sensors
Electronically control the brakes, differential, engine, and transaxle to help reduce tire spin upon acceleration on slippery pavement
Traction control systems (TCS)
A conventional hydraulic brake system is combined with an electric drive system of the hybrid’s driveline.
Regenerative braking system
car pulls to the left side while braking only.
stuck in passenger caliper wheel cylinder.
It feels as if the brake pedal is soft or slowly drops.
A spongy brake pedal
A computer that uses inputs from the wheel speed sensor to control the operation of the electro-hydraulic modulator.
ABS control module
Electronically links the steering, suspension, braking, and traction control systems to prevent a loss of vehicle control.
Stability control system
It is a hydraulic-piston pump that develops fluid pressure for the hydraulic brake system
Master cylinder
car pulls to the right after braking
Two answers are possible!!
stuck out caliper on the passenger side. (most likely) or collapsed. The brake hose is damaged on the passenger side
Brakes remain partially applied when the brake pedal is released. The brakes will overheat if the vehicle is driven very far.
Dragging brakes
Most vehicle manufacturers specify brake fluid that meets what specification
DOT 3 or 4
Measures the amount of hydraulic pressure in the brake system.
Brake Pressure sensor
Rubs against the stationary brake shoes to stop or slow wheel rotation.
brake drum
brake light not working tested bulbs and wiring they tested good
bad brake light switch
The first step in the brake system diagnosis
Visual Inspection
Combines the control module, proportioning valve, metering valve, and pressure pump into one assembly.
ABS Module
The three ABS pressure control stages?
Isolation, pressure reduction, pressure increase
Equalizes braking action at each wheel during light brake applications.
Metering valve
loud squealing sound
bad break pads
