80 - Brake System Technology
brakes apply too quickly, even with light brake pedal application
Grabbing brakes
ABS system
which is mounted in the dash, alerts the driver to an ABS malfunction.
ABS warning light
confined brake 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
are magnetic pickups 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 regenerative braking system provided by the hybrid’s driveline.
hybrid brakes
car pulls to the left side while braking only.
stuck in passenger caliper wheel cylinder.
feels as though it is connected to a spring or a rubber band.
A spongy brake pedal
a small 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
is a hydraulic-piston pump that develops fluid pressure for the hydraulic brake system
master cylinder
car pull to the right after braking
2 answers possible!!
stuck out caliper on passenger side. (most likely)
or collapsed Brake hose on passenger side
remain partially applied when the brake pedal is released. The brakes will overheat if the vehicle is driven very far.
Dragging brakes
a conventional master cylinder with power assist for operating brakes under normal conditions,
master cylinder-booster assembly / brake booster
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
A fast and accurate way of checking many components of the brake system is
brake pedal check.
combines the power booster, master cylinder, and modulator units into one assembly. All these units are mounted together.
integrated ABS
the major units are separated. A conventional booster and master cylinder are used with a separate electro-hydraulic modulator.
nonintegrated ABS
equalizes braking action at each wheel during light brake applications.
metering valve
loud squealing sound
bad break pads
