Rear Disc Brake Service 'how To'

[spridget]

Items Needed

• 15mm socket and box end wrench
• 13mm socket and box end wrench
• High Temp Silicone grease

1. Raise and support the rear of the vehicle. Chock the front tires.
2. Remove the wheel.
3. Remove the thin metal retainer nut on the stud, if equipped. (holds the rotor in place)

4. Remove the two 13mm bolts from the brake caliper slider pins.
   [attachmentid=22967]
5. Pry the caliper and pads off of the rotor. The rotor may have developed a ridge on the outer circumference. You may need to file the ridge down before you can remove the caliper.
6. Discard old pads.

7. Remove the two 15mm bolts from the caliper bracket.
8. Remove the rotor.
9. The caliper piston must be screwed back into the caliper bore. Use a caliper piston tool and rotate the piston clockwise. The slots in the piston must be at 12 and 6 o'clock to line up with the pad.
   • Reattach the caliper bracket and loosely tighten.
   • Reattach the caliper to the bracket and loosely tighten.
     [attachmentid=22969]
   • Use a caliper piston "box tool" or caliper tool to rotate the piston.
   • Remove components.
10. Remove the slider pins from the bracket. Be careful not to damage the rubber boots.

11. Clean slider pins and slider holes on the bracket of old grease and rust.
12. Liberally apply high temp silicone grease to slider pins and holes.
    [attachmentid=22971]
13. Reinstall slider pins and boots in the the caliper bracket. Make sure the flat side of the slider is in the correct position.
14. Install new or resurfaced old rotor. Use brake cleaner to remove any oil from the rotor surface before installing. Anti-seize grease around the hub and rotor center hole will prevent the new rotor from rusting to the hub.
15. Use a lug nut to hold the rotor in place.
    [attachmentid=22972]
16. Install the caliper bracket with the two 15mm bolts. Torque to 65-87 ft lbs.
    [attachmentid=22973]
17. Install the new pads. Use high temp silicone on the pad's back and sides (anywhere the pad makes contact with the caliper). This will prevent squeal and dragging.
    [attachmentid=22974]
18. Slide the caliper down over the new pads.
19. Make sure the pad next to the caliper piston is correctly seated into the piston slot.
20. Install the two 13mm slider pin bolts. Torque to 23-25 ft lbs
    [attachmentid=22975]
21. Mount wheel and torque to 85-100 ft lbs.

hey what's up. i'm kinda new to ttc...i just have a question about the rear disc brakes...is there a kit to cahnge from my rear drum brakes to disc brakes and if there is where do i get it from. however if not then is there a way to mod my taurus so i can run disk in the back??

Check out the link to the Wiki above. It's very easy to change from drum to disc, you just need to scavenge the parts from a junkyard and purchase a few new disposable parts.

hi,

good info,

be sure to use a brass brush to clean off those pins,
if they are too corroded, toss them otherwise you will
not be able to remove them the next time,
had to drive to four parts stores to get that
bracket that the caliper mounts to.
dang part was made in S. Korea by Dorman.

Great write-up! This is better than any aftermarket service manual.
