QuestionI would like to replace the front rotors on my 03 Discovery. When I tried to remove them, they would not come off. Do I need a puller for this? Are there any seals under the rotor that should be replaced?
Thanks,
Steve
AnswerHi Steve,
here is some info that you can use for you '03 Disco:
Brake disc - front
$%70.12.10
Brake discs must be renewed in pairs, unless one disc requires changing before 1000 miles (1500 km) from new.
Remove
1. Raise front of vehicle.
WARNING: Do not work on or under a vehicle supported only by a jack. Always support the vehicle on safety stands.
2. Remove road wheel(s).
3. Remove 2 bolts securing brake caliper to swivel hub.
4. Release caliper and tie aside clear of brake disc.
CAUTION: Do not allow caliper to hang on brake hose.
5. Remove screw securing disc to drive flange.
6. Remove brake disc from drive flange
Refit
1. Clean mating faces of drive flange and new disc.
2. Fit brake disc to drive flange, fit screw and tighten to 13 Nm (10 lbf.ft).
3. Clean mating faces of caliper and hub.
4. Fit caliper, and tighten bolts to 175 Nm (129 lbf.ft).
5. Fit road wheel(s) and tighten nuts to 140 Nm (103 lbf.ft).
6. Remove stand(s) and lower vehicle.
What some DIY'er do (and truly professional mechanics who care) is to inspect the wheel bearing and, if necessary, clean and repack the bear with the appropriate grease.
The hard part is separating the disc from the hub assembly.
On my '95 Disco, I carefully (CAREFULLY) tap around the area with a hammer (wrapped in a clean soft cloth) and slowly the two will separate.
On your '03, I've never done this. It would appear that once the screws are removed that hold the disc to the drive flange, the disc should eventually separate. Perhaps some "love taps" should be applied.
Best of luck,
