I had a E3 valve installed on my MC5 I noticed no great increase in braking. now after we have been on the road for a while, when I touch to brake pedal it almost locks the brakes up. I wonder if this is the valve or something else? Also when we release the parking brake there is lots of air escaping under the floor. (where to valves are)
Any ideas? |

Hi Neil:
Just curious!!
Do your have an MC5, 5A, B, or C???
Application valves for all were not the same.

Hi luke
Mine is a 64 and just a 5. The valve was sold to me and installed by So. Oregon Diesel.They should know what they are doing?
I sent you a E mail asking where you were and never got an answer. Still wondering? Neil |

Hi Neil:
Unfortunately my MC5 parts book is missing???
However I do have every other MCI model after that.
The MC5a, MC5B & MC7 books (which takes us to the late 60's) all call for an E-1 brake application valve. The E-1 & E-3 are still available and we stock both.
Now Dave at Sr. Ore. Diesel has an excellent reputation and although I have never met him (we will finally meet in Arcadia at the Bussin 2003 rally), we have spoken numerous times on the phone & have referred customers to each other.
Now with an older coach, if it has changed hands a bunch of times, and many have, there is no way of knowing what parts have been changed, whether they were right or wrong before you bought the coach.
If Dave replaced what was there, but what was there was not correct in the first place, there could be a problem.
I will never knock another shop!!, because unless you are there, one never knows the entire story.
Another thought comes to mind from posts I have read where folks cobble together different rear brake chambers because the original DD3's are expensive. Well the coach may stop but is the system right!!!!!
Bendix Westinghouse develops an entire brake system with the proper valving for each bus manufacturer.
If you change part "A", what does it do to the rest of the system and most importantly, is the vehicle SAFE??????
I can't solve your problem over the internet but offer the above as "Food for Thought".
I Hope it HELPS!!!

So Oregon did just what I asked them to do. The E3 valve is an upgrade from the E1. I am told that the E1 puts more braking to the rear wheels. The E3 is supposed to put about 65% to the front, like the newer buses. I don't think it's the valve. Thank's NEil |

Neil,
Your push/pull parking brake valve may be the problem. When it needs rebuilt/replaced air will escape through the anti-compounding circuit back to the E3 and escape out of the exhaust port and out of the quick release valve for the front brakes which is also located under the floor in front.
FWIW
