I was attempting to do my friends 98 GLE rear rotors and pads yesterday. The passenger side caliper would not come off the rotor. At all. I disconnected the ebrake cable, removed the two 17mm bolts, and even pried a little. Checking to see my procedure was correct, I released the cable from the driver side, removed the bolts, and the caliper would slide off near effortlessly.

He complained of a noise in the rear of the car, and with the caliper being so stuck, I'm thinking it's frozen on. 98 GLE with about 120k on the clock. Can anyone confirm that the caliper is frozen? Or is there something wrong with my procedure.

Any help is apprecaited, thanks in advance.

 

new caliper time....they freeze up often...especially with 120k...i have done both of mine....does the piston turn at all

 

I didn't even take it off the rotor. I wanted him to be able to drive home. I'll get a pair of calipers, and check the piston movement once I have it off the car. These are groved pistons correct? As in, I either need a special tool to spread and twist, or needle nose pliers to twist as I push, right?

Thanks for the quick reply!

 

yessir they are....no need to push though...its like a screw just twist

 

Yeah, the piston doesn't just push right in....you need to turn it AS you are pushing it in. Some people have used needle nose pliers but I'd be too scared of marring the outside of the piston and consequently having the seal get some tears. There is a tool you can buy that attaches to a rachet and fits inside the piston, allowing you to turn it:
