2014 JK
I have had jeep brakes serviced at Brakes Plus
they did something during repair to now cause problems
Rear passenger wheel locks , and blows the piston out of caliber
Also the ABS module keeps blowing out the round ports on the side

these issue only happen in the snow when the ABS kicks in

The local Jeep dealership can not find the problem nor can they fix it

They have replaced Master cylinder, calipers, and ABS module
I have not blown piston out of the caliper lately
but the ABS module blew out the first time i needed it to work

Has anybody ever seen the this issue ?
The dealership says they have never seen this before
