Just recently had to change a rear lower control arm on the drivers side. A week or so later today Im driving and the transmission keeps acting confused and it feels like a good misfire. Pull over and the car wont move. I hit the gas and the rear drivers caliper is locking up... Flip the ebrake on off and drive a little more its okay. Then the same thing repeats itself a mile later. I have rebuilt rear calipers from rock auto about 2yrs old. I guess thats not the best idea as now im out of service? I happen to use the ebrake the night before not sure if its possible the cable can lock up? Or can this be something ABS related? Plan to turn the caliper in and see if it happens again if so get a new OEM caliper. My experience with the LS is the rear calipers seems to stick. To top it off I have a horrible creaking noise from the master cylinder area when depressing the brake pedal. Some claim this is the guide pins not being lubed or the rotors.. i have fairly new OEM rotors and pads. Took it all off and and greased it again no difference.. any ideas? Is there something else in the linkage to lube? Or is this what a bad cylinder sounds like? Front caliper and boot is totally fine & was able to compress the piston easily. Maybe grease the piston? Can always swap rotors & pads but doubt that is my issue. Trying to see what I can do before going to the shop. Had this creaking once on my mustang but it went away.
