disciplerocks's B2 build thread

[Boggin]

is that the big box where all the wires join down on the drivers side frame rail?

 

[disciplerocks]

Yeah right in front of the fuel filter. has brake lines going to it.

 

[NMB2]

so is this what you guys are bypassing?

 

[RangerSVT]

No, thats the proportioning valve with a pressure sensor on it. Different years vary, I've seen em in the back on the back side of the fuel tank on the frame rail, along the frame rail in the area of your trans crossmember, and newer models are up on the firewall. I'll be bypassing mine when the new axles go in. Wait, they're going in now I better get to bypassing !!

I know exactly what it is, and on all 3 of my B2's it was in the location they are describing. I was making sure they weren't bypassing the prop valve.

its dumb to bypass it, it will save your ass if you lose a brake line.

 

[RangerSVT]

Yeah, its easy to mistaken the prop valve for the ABS module

[disciplerocks]

Its not dumb, if it doesnt work. I would like to have rear brakes for once.

Dustin, that's got to go back in! Propo valve. They do occasionally go bad though, which could affect your no rear brakes.

 

[disciplerocks]

No thats not it. I dont have whatever that is. The unit I am bypassing only has 2 brake lines. One from rear axle, the other from the master cylinder. Its has a 4 wire plug in the middle.

 

[disciplerocks]

This is it

and if you know how to drive, and can keep your brakes from locking up... you can stop a lot faster than with abs locking and unlocking your brakes. its awesome for pulling trailers- non-abs helps a lot.. i wouldn't consider putting it back on my truck at all. my b2 and ex have been abs-less for about 5-6 years now..

If we were infact talking about your Prop valve, yes, it is stupid to remove it. Number 1, having full power going to your rear drums will destroy the wheel cylinders and your pads. and number 2, if you lose a brake line, there is a piston inside that will close off that end. Which alot of times can happen, leaving the rear without fluid, you Have to reset it.

You do have a prop valve, but what you pictured is not it.

being ABS-less is no big deal. I was making sure you guys werent removing your prop valves.

 

[disciplerocks]

If I have one of those, I dont know where it could be. I followed the line from the master to the bad unit I am bypassing, then from that to the rear axle. Never seen that thing. I do remember seeing one on my Explorer donor though.

Mine is tucked up in the frame rail right under the drivers side door.

On a van we had, rear brake line went out and lost the rear brakes but the valve made it so that we could keep our front brakes till we got home. Well when my dad and I tried to bleed the rear brake, couldnt get fluid to come out the lines. The solution that I did was put a vacuum on the bleeder screw (aka suck on it with a long clear tube) when it was open and for some reason allowed fluid to go through the valve and only then were wer allowed to bleed the rear brakes. And yes this van did have ABS.

you can do that, or what I usually have done is when you re-fill the master... pump the brakes a few times. then violently hammer the brakes repeatedly, sitting in the driver seat. It'll pop the valve back to center.

I was just looking out for you guys, making sure you werent doing things you didnt have to/are unsafe.
