14. Caliper Installation
1. Re-install the caliper onto the brake spider using four (4)
new SAF
®
specific brake caliper bolts
(Figure 37):
a. Pre-torque the bolts to 88 ft.-lbs. (120 N•m) from
inner bolts to outer bolts using a size 24 mm socket.
b. Verify the pre-torque of the bolts a second time, and
if necessary re-tighten all bolts to 88 ft.-lbs. (120 N•m).
c. Final torque from inner bolts to outer bolts to
331
± 22 ft.-lbs. (450 ± 30 N•m).
NOTE:
The caliper is connected to the disc brake spider
using four (4) SAF specific bolts: three (3) standard
bolts and one (1) shoulder bolt
(Figure 37).
The shoulder bolt is located at the top mounting
hole whether the caliper is installed forward or
rearward of the axle.
IMPORTANT:
Make sure that the brake caliper is mounted
on the correct side of the axle. The correct
position can be identified by the lengths
of the guide pins on the caliper unit. The
longer guide pins should be positioned
on the bottom of the caliper unit when
installed rear of the axle and on top when
forward of the axle
(Figure 38).
2. Re-install the SAF
®
brake chamber by following the
instructions in SAF
®
Brake Chambers Installation and
Service Guide XL-SA10062IM-en-US available on the
internet at www.safholland.us.
3. Re-install the ABS sensor by following the instructions
detailed in Section 16.1.
4. To enable the ABS sensor to function properly press the
ABS sensor against the ABS toner ring at the hub unit to
eliminate any clearance between these parts.
IMPORTANT:
After replacing the rotor, verify that the
brake system is functioning properly.
Failure to verify brake system function
after rotor replacement could result in
brake malfunction which, if not avoided,
could result in death or serious injury.
