What I know now could have saved some money.

[Cedar41]

We have our Coach back and our brake problem fixed even though we are not sure what fixed it. The HydroMax pump was replaced and that did not release the brakes all the way. We replaced the Power Steering pump and that somewhat released the brakes (with in 1/4 to 1/2 inch)?
All the Hydraulid fluid was replace, we sent the HyrdroMax to WRV and they put it on a new coach and said it worked as normal The Bosch Rep wanted the Hydromax sent to them so they could bench test it to make sure. We have sent the Power steering pump to Dallas to have it tested.

Now, the pedal is acting normal, not sure why.

What we should have done was take th Power Steering pump off first and have it tested before we went to the expense of the Hydromax replacement. (Labor and parts much more costly on this part.)

But, that was not how we were advised to do it. WRV has not had this problem so they were "shooting from the hip" too.

We added a grease zerk and Eng Mike is going to help me post a photo to show you where. We also added a spring to the end of the Hydromax and after we get the "go" from the bosch rep we will post that photo.

WHAT I KNOW NOW for sure, if you smell anything like hot brakes
put your foot under your brake pedal and see if you can pull it up. That way you will not burn up the ABS sensors and scare you to death.

If you have any problems PM us and we may be able to direct you.

We have to thank Eng Mike for all his help and I must say WRV really did step up and help us and we are out of warranty.

Congrats on a satisfactory conclusion to this really tough problem! Ya'll sure have had more than your share of of them. Knock on wood for you and all the rest of us for the future.

Thanks for the information.

P.S. Surviving 106 degree weather in Moab UT this week - are we crazy or what?!?

Lana,

Can you explain how the power steering pump affected the brakes? I followed your original thread, but don't recall the pump being suspect

Thank You

[Dave Fernandez]

Hello Jim:

The Power steering pump/Hydraulic pump controls the power steering, hydra-boost and the fan. They use one pump to run all of the above.

Thank you Dave!

BTW, followed your recommendation on Acacia RV Services. Greg and his shop are great, very happy with their service.
