This is not my trade but I do my own maintenance on my vehicles :thumbsup. From what I read, the zero loss does not address my symptoms. The only items I have not replaced are the steel lines (again, in good shape), the service brake cables (good condition) and the "control valve" on the rear circuit of the MC (how do you test that?).Īs far as the zero loss booster, that only corrected the slow, creeping pedal effect, right? I have that, I can live with that (Not worth it to me for $150 - $200). Hub bearing and seal are good at the moment. 006 shim and the drum is back within spec. The only oddity is that the face of the driver-side rear hub run out is out of spec by. I don't mind a firm brake, I just want the vehicle to match what I am doing. Pedal travel is improved but it is still 33%-50% before the brakes start to engage and most of the time I'm standing on them to stop the truck in a short situation. I bit the cost of that MC and got a 1 1/4" MC. You needed full travel just to bring the truck to a stop. With the 1 1/8" MC, the pedal went 85% before the brakes even started to engage. I've tried all the tricks for gravity, two man and pressure (not vacuum). The last brake service, I went through 40 oz of fluid to make sure the air is out. I have probably bled through a total of 3 gals of DOT 3 fluid since I had the truck. I do intend on replacing it but I want the brakes to be A++ before I add that back into the system. Yes, yes, living on the edge but I've driven non-abs vehicles before.
It is hydraulically bypassed at the moment. The RABS valve had rust and junk in it it will need to be replaced. It's been like peeling a never ending onion to try to get the brakes to work. It looks like they were replaced in the not too distant past.īy the way, yes, all of this had tested bad or was found below spec. I even confirmed the push rod on the booster is within spec. New booster (not the zero loss) and vacuum pump. New master cylinder (x2), 1st was 1 1/8" bore the 2nd and current is a 1 1/4" bore. Rear brakes are new drums, shoes, cylinders, hardware. Front Brakes are new rotors, calipers, pads, hardware. Service Brake cables in good shape (not binding or anything). Service Brakes do work (but again can't lock up the rears). Here is what I have done:įront and rear brakes are new, adjusted and seem to be working (I hear/see them working while bleeding). It stops nowhere near as quick as I think it should be.
:read: My issue is that I can not do a "panic stop" if wanted or need to. I have read a lot of threads on here and other forums about the brakes. I have gone through every aspect of this system and I am stumped. Since day one I have been chasing my tail with the brakes on this thing.
