BRAKES - FRONT - SHUDDER - REVISED SHOP MANUAL DIAGNOSTIC PROCEDURE
MERKUR 1985-86 XR4Ti
When diagnosing a report of brake shudder on the Merkur XR4Ti, it is important that the diagnostic procedure provided in the Merkur XR4Ti Shop
Manual, Section 12-01, page 21, be closely followed. If the condition is mostly noted at highway speed with a light brake pedal application, the cause is
most likely to be front brake rotor thickness variation. This condition would be felt by the driver as a steering wheel oscillation and vehicle shudder
during light brake applications.
Please note that the specifications listed in the 1985-86 Merkur XR4Ti Shop Manual on page 12-01-25 and 12-20-15 for maximum allowed rotor
thickness variation are incorrect. The specifications should read as follows:
0.01 mm (0.0004 in.) maximum thickness variation. If these readings vary by 0.01 mm (0.0004 in.) or more, the rotor should be replaced.
Please mark your copy(s) of the XR4Ti Shop Manual with this revision.
