Need Help with Pacbrake

(1/4) > >>

Les Brandt:
After spending a wack of money replacing all the rotors, calipers and brake pads on our new to us 2001 Beaver, I wondered how a coach with only 39,000 miles can need a full brake job. After finding out on our last Monaco that the Pacbrake was seized, I decided to look at the Packrake on the Beaver and sure enough seized up solid.

I really have to question if people realize that the exhaust brake needs maintenance. It is a valuable braking tool and saves your brake system not to mention, possibly your life on a steep downgrade.

Our coach has a CAT 3126B 330hp engine. I need to replace the exhaust brake. We tried to free it, soak it, bang it and nothing works to free it. I need to replace it. It's a turbo mount style.

Anyone know where I can get a used one? Lots of new ones available obviously.

You might want to review this old thread from the Forum in case yours might still be salvageable

Thanks Joel.

I did a search yesterday and read everything on the forum. I was kinda hoping there was something current someone knew. Like a place that was giving away new Pacbrakes for "free". LOL

I do not know if you mean the butterfly is froze closed or partially closed or the air ram is somehow froze but I had a butterfly that was sticking closed. I would come off a hill with the exhaust brake on then hit the bottom give it throttle and no throttle or very little as the butterfly was stuck partially closed. My remedy was I took the exhaust brake off behind the turbo and disconnected the tailpipe. Took the exhaust brake to an automotive machine shop. They drove out the pins and took the butterfly out, honed the inside of the exhaust brake and ground the carbon off the butterfly, oiled and put it back together. Cost me less than 100 dollars and works like new.

Thanks Gary.

The butterfly valve is seized open. The shop removed the brake and saturated it overnight in penetrating oil and they tried using a battery of tools on it to free it. Including air hammers. All it has done is disfigure the parts. I think she's a goner as far a freeing it. I tried using a 3 pound sledge and a chisel and the only thing that moved was me when the hammer glanced off the chisel and hit my hand by the wrist.
I think I invented a few new words yesterday when that happened! LOL
