| Brakes
At Midway Excel Tire & Auto Centres, we
ask, “If your brakes aren’t stopping you, what is?”
Midway will ensure that your brakes are in perfect working order
to do the job they are meant to do.
Warning Signs*:
- Brake light comes on
- Your vehicle pulls to one side when braking
instead of stopping in a straight line
- When applied, your brakes grab, causing jerky
stops
- Brakes grind with continuous loud metallic
noise when applied
- Brake pedal is either mushy or very hard
to depress
- Brakes must be pumped to work properly
- Wheel(s) are excessively hot after short
drives
- Brake fluid leaks are seen around any wheel
or in engine compartment, near master cylinder location
- Brake fluid very low or very dirty looking
What Midway Excel Tire & Auto Centres
service includes:
- Inspect the brake system for lining wear
- Measure drums and rotors
- Check calipers and wheels cylinders for
free operation
- Machine drums and rotors if required
- Inspect wheel bearings and repair if required
- Inspect master cylinder and brake hoses
- Install quality brake linings if required
- Inspect and adjust parking brake
- Top off brake fluid level
- Road test the vehicle to ensure all settings
are correct
There
are two components within the brake – Hydraulics and Friction
Materials.
Hydraulics
Master Cylinder
By applying pressure to the brake pedal, the master cylinder pushes
brake fluid to the wheel brakes by creating hydraulic pressure.
Brake Lines and Hoses
From the master cylinder, brake lines and high-pressure rubber hoses
send the pressurized brake fluid to the wheels cylinders and calipers.
Wheel Cylinders and Calipers
These are the hydraulic cylinders that apply pressure to the friction
materials, causing your vehicle to stop.
Friction Materials
Disc Brake Pads and Drum Brake Shoes
These brake linings are composed of high temperature materials that
create the friction that stops your vehicle.
Types of Brakes
Disc Brakes
Disc brakes consist of a disc brake rotor, which is attached to
the wheel, and a caliper, which holds the disc brake pads. Hydraulic
pressure from the master cylinder causes the caliper piston to clamp
the disc brake rotor between the disc brake pads. This creates friction
between the pads and rotor, causing your vehicle to slow down or
stop.
Drum Brakes
Drum brakes consist of a brake drum attached to the wheel' a wheel
cylinder, brake shoes and the brake return springs. Hydraulic pressure
from the master cylinder causes the wheel cylinder to press the
brake shoes against the brake drum. This creates friction between
the shoes and drum to slow or stop your vehicle.
Parking Brake
The parking brake uses cables to mechanically apply the brakes (usually
the rear brake.) This is used to prevent the vehicle from rolling
when not being driven.
Anti-Lock
Brakes: A System Built For Safety
Computer-controlled anti-lock brake systems (ABS) are a recently
developed safety feature. When sudden stops are made, the ABS prevents
wheels locking up. The system is comprised of wheel-speed sensors
that monitor wheel rotation, computer-controlled hydraulics that
pulse the brake on and off rapidly, and the onboard computer that
controls the process.
