#22 of 31 Re: Pads or Rotor? [imidazol97] by jipster Apr 12, 2008 (5:41 am)
Replying to: imidazol97 (May 25, 2006 8:20 am) An update. It's been about 2 years since I had my rotors turned, thus far I have had no further problems with them. I had my brakes checked about 4 months ago by the dealership, they said everything was fine.
#23 of 31 rear disk brake calipers by oldwino Apr 23, 2008 (3:41 pm)
My son has a 96 regal with 4 wheel disks. Went to put new pads on all 4 wheels. Had no problems with the front. The caliper pistons easily retracted with a c-clamp. Got to the right rear and could not get the piston back at all. The parking brake was not engaged. Wouldn't of gotten the caliper off, if it was. Is there some trick to retract the piston or is it likely frozen? Should it press straight back like the front calipers? Or does it rotate as it retracts? Unfortunately, we didn't have the time to check the left rear for comparison as he had to go. Had a heck of a time getting it back on with the old pads as the rotor was a little worn and had to pry the caliper off with a screwdriver to start with. Any info would be greatly appreciated. Thanks.   Replies to this message: Mr_Shiftright (Apr 25, 2008 10:27 am)

Replying to: oldwino (Apr 23, 2008 3:41 pm) 1. Remove 2/3 of brake fluid from master cylinder reservoir.    2. Raise and support vehicle.    3. Mark relationship of wheel to axle flange, then remove wheel and tire assembly.    4. Remove bolt and washer attaching cable support bracket to caliper body, Fig. 2.    5. Remove sleeve bolt and pivot caliper assembly up, Fig. 3. Do not completely remove caliper assembly body.    6. Remove outboard and inboard shoe and linings and two pad clips from caliper support.    7. Using a suitable spanner type tool in piston slots to turn piston assembly and thread it into caliper body assembly.    8. After bottoming piston, lift inner edge of boot next to piston assembly and press out any trapped air.    9. Ensure slots in end of piston are positioned as shown in Fig. 4 before pivoting caliper body assembly down over shoe and linings in caliper support. Use suitable spanner type tool to turn piston as necessary.   10. Install pad clips and outboard and inboard shoe and linings in caliper support. Ensure wear sensor is on outboard shoe positioned downward at leading edge of rotor during forward wheel rotation.   11. Pivot caliper body assembly down over shoe and lining assemblies being careful not to damage piston boot on inboard shoe.   12. After caliper body is in position, recheck installation of pad clips. If necessary, use a small screwdriver to reseat or center pad clips on support abutments.   13. Install sleeve bolt and torque to 20 ft. lbs.   14. Install cable support bracket and torque bolt to 32 ft. lbs.   15. Install wheels and tires aligning previous marks, then lower vehicle.   16. Apply approximately 175 lbs. of force to brake pedal three times to seat shoe and linings against rotor.
#25 of 31 Brake light problems with regal custom by petegreb Nov 23, 2008 (10:27 am)
I have the same problem. The brake light by the spoiler comes on but the lowers brake lights don't come on.   Can anyone help me? Replies to this message: mech21 (Dec 12, 2008 11:08 am)

Replying to: petegreb (Nov 23, 2008 10:27 am) It could be in the turn signal switch. On our '94 Regal, if you pull the turn signal toward you slightly (stopping short of switching to high beam headlights) as you press the brake pedal, the main brake lights come on. I can't offer any tips to disassemble the steering column to fix or replace the switch...haven't tried it yet.
#27 of 31 Regal Rear Brake Issues by armes Apr 27, 2009 (5:16 pm)
I have worked on several Regal ( 1996 ) which had premature wear and bad rotors on one or both sides. From what I have been able to determine, the problem lies with the design of the caliper slide system. All problems I discovered were related to the top caliper slide bolts. This is the one which is covered by the cap and is inset into the caliper.   Every vehicle which had problems had locked slides due to the top bolt being bent where the threads and shank of the bolt intersect. This bolt is too small to handle any lock up of the brakes and is even more fragile when the brakes are applied and the wheel hops on a rough road or pot hole. The sheer force of heavy brakeing appears to bend this top bolt which, once bent a little, becomes weaker with every braking and bends more until locking the slide.   I highly recommend replaceing all bolts when replaceing the rear pads.

#29 of 31 2002 regal brake pulsation by ljlittle Sep 22, 2009 (10:30 am)
I had complete brake job (new pads & rotors all 4 wheels) after aprox 1500 mi experienced a bad pulsation. Rotors were removed and turned, it was ok for about 500 mi then started all over. Tech says it is the front wheel brg. is slightly loose and this is causing the problem. He says this is a expensive job because it has ABS. Help
#31 of 31 brake warning light by regalgs04 Oct 20, 2009 (3:07 pm)
I own a 2004 Regal GS with about 60K miles. I need to know if I can repair the device inside the brake fluid reservoir that triggers the low level switch or if I can replace the reservoir itself without removing the master cylinder. thanks in advance for any help.
