Disk Brakes
This causes a brake vibration when braking
High spots on the rotors/ rust on the rotor.
Rotor thickness variation.
Brake Fluid is primarily this color
What is: Yellow / clear / amber
Where do you apply oil?
To the pad supports behind the brake hardware.
What does brake grease do?
What is: Allows the pads movement so that they do not make a squeaking noise.
The piston that applies the shoes in a drum brakes are called
Wheel cylinder
This applies the brakes at the front wheels.
What is the Caliper
**** DAILY DOUBLE****
This is the most common type of brake fluid
What is: DOT 3
May cause a pull to when brakes are applied.
What is a seized slide pin?
What is a blocked brake hose?
This is a copper based product applied to the pads to help to stop them from sticking
What is: Anti-seize compound / Brake Grease
**** DAILY DOUBLE****
How is the parking brake applied in a drum brake?
A cable pulls on a lever which pushes the shoes against the drum / Electronically
This holds the pads in place
What is: Caliper bracket
This brake fluid is only used for Racing applications.
DOT 5 or DOT 5.1
What are the flimsy metal hardware parts for?
They are used to help reduce noise from the pads and to keep them in place.
This product is used to lubricate caliper slides.
What is: Dielectric grease / Purple Silicone Grease
Which wears out faster, drum brake shoes or disc brake pads and why?
What is: Discs, because drums only do 30% of the braking
These can seize and cause the pads to not be able to slide
What are Slide Pins?
When this enters the brake fluid, it can create a spongy pedal and cause poor braking
Air
True or False: Pads that are worn out should be serviced, not replaced.
False, they should be replaced
This will happen if anti-seize gets on the pad surface
What is: Poor braking, the pads won't grab as efficiently
True or false: Drum brakes are harder to replace than disc brakes.
What is: TRUE
These are high end rotors. They are specially designed to keep the rotors cooler than a normal rotor
What are Drilled and Slotted rotors?
When this enters the brake fluid, it lowers the boiling point drastically
Water - brake fluid is hygroscopic and attracts water from the air.
**** Daily Double****
What does a brake service involve?
What is: Taking brakes apart, lubing slides, cleaning up the clips and pad supports, adding anti-seize, and/or brake grease and machining or replacing rotors.
Brake fluid is leaking from the caliper, what should you do?
Replace the caliper
The machine used to cut drums is called
A brake Lathe
