If u can get her to an authorized workhorse service center, u may have a recall issue u can get fixed for free.

U do have one or more frozen calipers, please be very careful
The 1998 P30 is a chevrolet chassis, not Workhorse and was never a part of the recall.
Workhorse never used the P30 as a motorhome platform.

P-30 Chevy chassis

This is one of the last of the P-30 Chevy chassis; any Chevy truck shop should be able to diagnose the problem. Most of the P-30's front brakes were a little undersized on the bigger and heavier coaches. Back in the day I used to sell lots of coaches built on this chassis; the ride was much better than the Ford of the same era. The 454 engines created a lot of exhaust heat affecting plug wires and brakes. Hope this helps. DACOTAH

We ran into this a lot with the P32 chassis. Chevy used a wide meal clamp on the rubber brake hoses. As the hoses aged they tended to swell. The clamp would not let the hoses go out, so they swelled shut. The pressure goes thru OK but will not release when you take your foot off the brake pedal. It is easy to check this. Crank the motorhome, press the brake several times. Extend the jacks until the front tires are off the ground. Stay clear of the motorhome in case the jacks should come down. Try to turn the wheels. They should turn. If not the brakes are staying on. To double check that it is the hose, let the jacks back off and loosen the bleed screws without touching the pedal. There should be no pressure in the hose. If it squirts out, you have pressure in the hose.

This is not a Ford or Chev or Workhorse problem. I had a simlar problem on my '89 E350 with a brake hanging up. My mechanic explained to me the idea of the brake fluid absorbing water from the air and causing rust inside the brake parts. The master cylinder and brake cylinders are the ones that get the problem. My MH was 3 years old when I had the first problem like this. I became a real regular on flushing brake fluid since then. This was also a part of the problem on the Bosch brakes on the WH. There was inadequate clearance for the piston in the caliper.
