OVERHAUL
Some vehicles may be equipped dual piston calipers. The procedure to
overhaul the caliper is e ssentially the same with t he exception of multiple
pistons, O-rings and dust boots.
1. Remove the caliper from the ve hicle and place on a clean workbench.
CAUTION - NEVER place your finger s in front of the pistons in an attempt to
catch or protect the pistons when applying compressed air. This could result in
personal injury!
Depending upon the vehicle, there are two different ways to remove the piston
from the caliper. Refer to the brake pad replacement procedure to make sure
you have the correct procedure for your vehicle.
2. The first method is as follows: a. Stuff a shop towel or a block of wood into the caliper to catch the piston.
b. Remove the caliper piston using co mpressed air applied into the caliper
inlet hole. Inspect the piston for scor ing, nicks, corrosion and/or worn or
damaged chrome plating. The piston mu st be replaced if any of these
conditions are found.

The normal automotive circuit differs from
this simple example in two ways.
First, instead of having a return wire from the bulb to the battery, the current
travels through the frame of the vehicle. Since the negative (—) battery cable is
attached to the frame (made of electrically conductive metal), the frame of the
vehicle can serve as a ground wire to complete the circuit. Secondly, mo\
st
automotive circuits contain multiple components which receive power from a
single circuit. This lessens the amount of wire needed to power components on
the vehicle.
HOW DOES ELECTRICITY WORK: THE WATER ANALOGY
Electricity is the flow of electrons - t he subatomic particles that constitute the
outer shell of an atom. Elec trons spin in an orbit around the center core of an
atom. The center core is comprised of protons (positive charge) and neutrons
(neutral charge). Electrons have a negativ e charge and balance out the positive
charge of the protons. When an outside forc e causes the number of electrons to
unbalance the charge of the protons, the electrons will split off the atom and
look for another atom to balance out. If th is imbalance is kept up, electrons will
continue to move and an elec trical flow will exist.
Many people have been taught electrical th eory using an analogy with water. In
a comparison with water flowing through a pipe, the electrons would be the
water and the wire is the pipe.
The flow of electricity can be measur ed much like the flow of water through a
pipe. The unit of measur ement used is amperes, frequently abbreviated as
amps (a). You can compare amperage to th e volume of water flowing through a
pipe. When connected to a circuit, an ammeter will measure the actual amount
of current flowing through the circuit. W hen relatively few electrons flow through
a circuit, the amperage is low. When many electrons flow, the amperage is high.
Water pressure is measured in units su ch as pounds per square inch (psi); The
electrical pressure is m easured in units called volts (v). When a voltmeter is
connected to a circuit, it is meas uring the electrical pressure.
The actual flow of electricity depends not only on voltage and amperage, but
also on the resistance of the circuit. T he higher the resistance, the higher the
force necessary to push the current through the circuit. The standard unit for
measuring resistance is an ohm. Resistance in a circuit varies depending on the
amount and type of components used in t he circuit. The main factors which
determine resistance are:
• Material - some materials have more resistance than others. Those with
high resistance are said to be insulato rs. Rubber materials (or rubber-like
plastics) are some of the most common insulators used in vehicles as
they have a very high resistance to electricity. Very low resistance
materials are said to be conductors. Copper wire is among the best
conductors. Silver is actually a super ior conductor to copper and is used
in some relay contacts, but its hi gh cost prohibits its use as common
wiring. Most automotive wir ing is made of copper.
