hard brake pedal fix?

ok, hard brake pedal, low braking power. its scary coming off the freeway or down a steep hill. front calipers n rotors look good. rear calipers look rusty around joints and pins. rotors are rusty. took it to local w/h shop today. they say can't find anything wrong! are theese people awake? anyway what else would cause a hard pedal and bad braking? i will try to take the rears down myself. any sugestions would be very helpfull. my 04 had wonderfull brakes. bought this one new a year ago march. going to wa. from az. soon so i need brakes for the big hills.
thanks dave

You are right to suspect that something is not right. If the rust is not being scrubbed off the rear rotors, then I think it is a safe bet that the pads are not making conact. That would explain the poor braking performance. I don't know why the pedal would be "hard".

Was there any explaination regarding the rusty rotors from the Workhorse dealer? Are you sure they actually checked the rears or did a test drive? ED

Perhaps a stuck piston or two in the caliper(s)? Would make for a hard feel pedal and a loss of stopping power.

Please go to the workhorse website and use the "rate this dealer" function to report your dis-satisfaction with the result of the service received. You should also call roadside assistance at 877-946-7731 and ask them to get involved. Assuming you are still in warranty, IMO, you need to INSIST that something is not right and you want another opinion. Please don't write off the entire company based on an independent dealer's failure to find the problem. ED

Hard pedal and low power suggests an issue with the brake booster system to me.

True story: (Well GM is a workhorse spinoff) I should know it's true as, well I"m telling it in first person (And I'm party of the part as it were)

Took my car (GM product) to local dealer, they commented on excessive pedal travel (I had noticed it too) had 'em look it over, twice, no problem found, did a minor adjustment, seemed to help a little. but alas, no joy

Finally put my mind to work on it,, NOTE: NOT my wrenches, my MIND. Sitting at a desk I begin to visualize the brake system (Front disc, not much there that could cause excessive pedal travel, rear drum. .AH HA, That has got to be it!!!!

Took car elsewhere (Than dealer) and told George (The assistant mangaer) have the technician mic the drums (Micrometer)

Watched the measurement.. Did not look at the readings just watched him do the job (he did it properly by the way, I dont' have the proper micrometer for this job)

Went in and ask George how much new drums would cost me

That, was that, 2 new drums, a new set of rear shoes, one new adjuster (i'd already done the other one) and ... Good as new
