BRAKES
Disc brake
A regular check of brake disc condition is most important; the disc should be
absolutely clean without any traces of rust, oil, grease or dirt and should not be
excessively scored.
Front brake disc diameter: 10.24 in. (TE, TC, TXC); 12.6 in. (SMR)
Front brake disc thickness (when new): 0.118 in. (TE, TC, TXC); 0.197 in. (SMR)
Brake disc thickness at wear limit: 0.098 in. (TE, TC, TXC); 0.177 in. (SMR)
Rear brake disc diameter: 9.45 in.
Rear brake disc thickness (when new): 0.157 in.
Brake disc thickness at wear limit: 0.138 in.
The disc distortion must not exceed 0.15 mm/0.006 in. (this measure is to be taken
with a comparator and with the disc mounted on the rim).
TE-TC-TXC Loosen the four fixing screws to remove the disque from the rim. When reassembling,
