BRAKE SERVICE PROCEDURES FOR 1994 Mercury Topaz AUTOMOBILES
Disc Brakes -> Front Disc Brakes -> Troubleshooting -> BRAKE ROUGHNESS
Vehicle: 1994 Mercury Topaz 2.3 L4 GAS
BRAKE ROUGHNESS
The most common cause of brake chatter on disc brakes is a variation in thickness of the disc. If roughness or vibration is encountered during highway operation or if pedal pumping is experienced at low speeds, the disc may have excessive thickness variation. To check for this condition, measure the disc at 12 points with a micrometer at a radius approximately one inch from edge of disc. If thickness measurements vary by more than ...

DRIVELINE, U-JOINT & CV AXLES REPLACEMENT PROCEDURES FOR 1994 Mercury Topaz AUTOMOBILES
CV AXLE SHAFT, Replace
Vehicle: 1994 Mercury Topaz 3.0 V6 GAS
If removing both righthand and lefthand driveshafts, install plugs T81P-1177B, or equivalent. Failure to do so may result in dislocating of differential side gears, requiring transaxle disassembly to align gears. Also, driveshaft removal and installation procedures are the same for manual and automatic transaxles except for the following: due to automatic transaxle case configuration, righthand driveshaft assembly must be removed first. Removal tool T81P-4026-A, or equivalent, is then inserted into transaxle to remove lefthand inner CV joint assembly. If only lefthand dri...
