Hi
I have a 78 Dodge Sportsman B300 24 foot motor home.
The body is great, the 440 runs well and the mileage is just under 100,000.

Two big bads are it has 16.5 tires and the rear brakes needed done a long time ago.
The rear brakes tend to stick after sitting for a time.
To unstuck requires the full throttle of the 440 if the motor home has sat for to long.
If I move it every month or so the brakes unstuck not to bad but at times drag for few blocks, sometimes lightly dragging to the point of a very hot hub.
Due to this it don't go far, just to the dump station when needed.

What do you guys figure the cost may be at the worst case scenario? To change the whole works, Including brake lines?
I will not be doing the work myself rather take it to a brake shop.

 

Best to have it all checked out an get an estimate for the repair.
But a full full brake job on one of those without hard lines is about $1,000.00 Parts and labor I would imagine..

But I think I would start out with a good System flush with a pressure bleeder,
and some rebuilt calipers up front. and new brake shoes and hardware kits out back, and see if that dint fix the issue.
Now note, that once your fully flush the system, these old ones tend to flush all the crap built up in them right into the wheel cylinders and calipers and cause them to start leaking and ruin the new shows.

So my 2 cents is... Brake line flush... New master.. new calipers and flex hoses.. rear flex hose, new wheel cylinders... new shoes... new hardware kits..
new fluid.. pack the wheel bearings and you should be good for the road. Add brake rotors and drums if needed.. Oh... and check them tires...

 

RacerHog please accept my apologies. I remember quite well posting this...just forgot where lol
Thanks so much for your info.
Your valuable 2 cents worth is what I was thinking.
Just getting on this now, been putting it off to long.
Goin for acouple of estimates this week. Hoping it works out.
Will let you know.
Wish I could keep the 16.5 tires but their old hard to find so they have to go.
Thanks, sorry for the delay.
Catch ya soon!

 

So nice to not have to check the rear view mirror for smoke & fire.

Both rear wheel cylinders, shoes, wheel adjusters, hardware kit, seals, one front caliper + hose.
$850 - parts & labor.

Thanks
