fill the master cylinder , pump the brakes until you have a hard pedal

go to the Right rear ,open the bleeder while, perso keeps pressure on the pedal until it goes to floor

I have been working on brakes , RV trucks all the same

for 34= years ,RV dealers tell you what you ant to hear

they have no clue on working on them, just sell

I told you how to do it but if you want the RV , let me know, I will opt-out

and take it to a RV service, for $105.00 HR
