Hoser quote "On the bigger trucks like your RV they use the power steering pump to supply you with power for your "power brakes" they don't use the vacuum booster you/they sure its working ok, I would think they could inspect all brakes and tell if anything needed replaced and not just parts change? Your rears disc or drum brakes? "
I didnt know the powersteering pump was part of the braking system. They didnt say anything about the powersteering pump, they did mention the master cylinder. I need to see if I have a manual on the P30 chassis, I have the P30/32 Chassis. Also I don't have the Autopark system that is prone to failure. If the RV was here I would go and have a look. I talked with the ,quote "Service manager" and said I cant a afford for his techs to throw parts at it until its fixed. He insisted the calipers were bad. Now that you mention the power steering pump is involved, when I apply the brakes its almost as if you tried to apply the brakes in a vehicle when the cars
Engine is turned off (no vaccum to booster). Ill have to go up there today and inspect before they start throwing parts at this thing. Can you think of anything else I might check out? Thanks Hoser. And it has drum rear brakes.
that's about all I know about them never had that much problem with RV brake system other than the usual that comes with age and not being used, master cylinders leaking out the rear seal, calipers sticking because of moisture inside the fluid then the caliper piston rust and sticks, rubber brake hoses, I try to bleed my brake system every year to keep fresh fluid in them, all the P30 RV's I have had I changed the brake pads when they get about 50% worn out since they do most the braking and I was always towing a trailer abusing the brakes.
Just changed both calipers and brake hoses and master cylinder on my RV last year, that and new pads think it was under 120 bux for all the parts from NAPA
Never had a problem with the rear drum brakes even after 100k miles, almost impossible to reach the bleed screws on the rear drums so I just bleed them at the TEE in the line at the rear axle snapping off a bleeder would make for a expensive all day project to replace.
