S15/T15 Jimmy 2WD V6-4.3L VIN W (1998)
Brake Rotor/Disc: Description and Operation
The front disc brakes use a combination rotor and hub assembly. The rotor and hub are combined on RWD vehicles. The rotor is separate from the hub
on S4WD and F4WD vehicles.
The rotor turns freely between the linings, until the caliper forces the linings against the rotor. The vented area between the rotor braking surfaces allows
for efficient heat dissipation.
