Help! Brakes are bleeding
I had my front rotors and calipers replaced about 2 months ago on my 98 ML 320. Now, the brake calipers are bleeding out in all four wheels, esp. in the front ones. The brake pedal is mushy. The brake fluid reservoir is still full. I checked under the car at all four wheel. The fluid is brake fluid. They are coming from the calipers, not the bleeder screw.

I think the mechanic I used in my small town may be jacking with the car. I brought it to him and he suggested that all four calipers need to be replaced due to "liability" reason. He doesn't recommend rebuilding the caliper.

How can this happen to all four calipers at the same time. Did the mechanic put wrong brake fluid and now it is eating up all the seals in the caliper? I did him a favor and he in turn did the brake job for free with me supplying the rotors and brake pads. I remember they were Zimmerman or Brembo rotors and Mintex pads. Therefore, we have no official transaction records of this brake job..

At this point, I don't trust him anymore. He seems to like to wholesale replace parts instead of diagnosing the problem.

Any input would be greatly appreciated. Thanks all.

Are they leaking from the seals around the pistons in each caliper?

Was silicone brake fluid used?

What brand of brake fluid was used?
