Question -
1999 Chrysler Sebring convertible:
The front brakes do not fully retract to the point where I must stop and let them cool before proceeding. This only seems to occur in warm/hot weather, and only after some time on the road.
What's up?
Answer -
Hi Bud,
The manuals give several possibilites for dragging front brakes:
Clogged master cylinder return port (clean out)
Incorrect booster push rod to master cylinder clearance (adjust, should be 0-0.25mm)
Faulty master cylinder return spring (replace)
Lack of lubrication of sliding parts (the caliper pin surfaces I would suspect) and finally one that I have learned about separately: a rubber brake hose at the caliper that has rotted along the interior lumen such that the fluid will not flow backwards as quickly as it flow frontwards (replace the hose(s)).
If it is bilateral I guess I would suspect the master cylinder issues, while if it unilateral I would suspect the caliper or the hose supplying the caliper. Those are the possibilities as far as I know.
If you have ABS there may be other reasons, so let me know if that is the case. The ABS system though is subject to troubleshooting using a diagnotic readout box which you may have to borrow from an Autozone or other retail parts store, or have it readout at a shop.

AnswerHi Bud,
It would be good to check the ABS controller memory for any faults that it may have noticed. If none are found, then the items I first identified should be considered.
You can get a memory readout by means of a jumper wire. If you reach under the dash to the right of the base of the steering column you will find a 16-pin plug, two rows of 8 pins each on the end of a cable. Hole the plug with the pin sockets facing you, and the tab on the long side of its shell facing down.
Insert a wire that is thick enoungh to make good contact into the socket at the left-hand end of the upper row. This is socket #1 (which might be labelled as such on the wire side of the plug?). Attach the other end of the wire to a screw or bolt that is screwed into a metal structural element of the car or to the - post of the battery so that you are 'grounding' pin #1. Then turn on ignition switch and observe the ABS warning light will come on and after a few seconds it may be begin to flash, pause, flash, etc. Count the number of flashes before each pause. Finally the ABS light will revert to simple flashing without pause. Repeat to verify that you have the correct counts.
Pair the numbers in the order they came out to form two-digit numbers which are the fault codes. Write back with the numbers and we can consider what to do next. If no flashing and pausing occurs then there is presumable nothing wrong with the ABS part of the brake system and the earlier items I suggested are in order.
