hello, we have a linde h35t 393 from 2003, and after working some hours the brakes gets stuck. we cheeked, and the brakes from right drive motors was loosing the pressure and in the service manual said to replace the seal of the piston brake. we changed the seals but the problem persist is losing pressure at the right brakes. we put the seal 182x3mm, is what the manufacture advice, but i have seen the tvh parts advice 2 seals 182x3 and 179x3, and the diameter of brake piston is 180mm, could be the 182x3 seal for new brake piston, and the 179x3 the piston brake have some wear, if i put the seal 179x3 would solve the problem?
