Hey all,
My 91 Crew Cab Dually has "questionable" power assist for the brakes. I'm trying to figure it out and I'm afraid I might have.
I tested the Vacuum at the Tee on the firewall and I had 5-10. I tested it at the pump (line direct from pump to gauge) and have 20 at idle.
I was under the dash today and I noticed a slight hissing sound. I pressed the pedal by hand and it stopped for a moment before resuming the hiss. It was a press and hold, not press and release.
I'm thinking my booster is leaking. What are your thoughts?
I want to do a hydroboost swap but it isn't in the cards right now. I'd consider it if I wasn't going to have to change out the pedal too, I found a used booster for $60.
I also will be installing an old hydraulic actuated trailer brake controller and need to order a tee for the line. Is the rear line at the master cylinder for the rear brakes? I think I read it's 7/16 thread but I want to get the right part the first time.
Thanks!
