Hi colleagues. As the title suggests, I have the following problem. With my Iveco Stralis 3 achs building material truck, this month is due to the tuv. As I drove there today and was on the brake test bench, I didn’t think right. When he wanted to check the parking brake, he determined that the values were different and the effect of the brake on the left was not sufficient. All other axles were not a problem. That there was no plalete for that was clear to me. Now the vehicle g 1 year old and nothing was done on the brakes. KM has now 94800 down. was 2 weeks ago at the customer service. Now my question would be what could that be? Service brake works without defects only determinedbreme haperts. Values were 1200 right and 300 left. Will visit the workshop tomorrow but they have made hints that they have no time for it. Thanks to you already.
