Verify please...raising the rod for the LSPV increases rear braking?

By raising the rod for the LSPV it increases rear braking. Correct? I invision the body lowering via load thus pushing the rod up. Thanks

 

I think that is how it works. Putting a heavy load in the bed would lower the bed toward the ground and essentially raise the rod at the lspv?

 

That’s how I see it. I suddenly am having a lack if rear brake issue and I’m assuming my problem lies here. I already installed the 2” bracket to accommodate the lift. Thanks

 

Yes, that’s how it works. The rear brakes need to be adjusted up as well. Depending on your weight, you might can go up more, and get better braking power.

 

There is a really interesting set of "On-Vehicle Diagnostics" in the FSM. It looks to involve attaching SST pressure sensors to the front DS and rear DS wheels, and then testing the pressure with and without load in the bed, and then adjusting the "fine-tune" on the axle end of the LSP & BV system:



I say interesting because I think "stock height" and "I'm lifted 2 inches" are relative to factory springs 20 years ago, and doubt any ability to correctly determine how much a truck is lifted at this point. I know we generally say, if you lift 2" get a 2" bracket and move on... but what if you did that originally (15 years ago) and now you've installed new springs, and the lift amount vs stock is (reasonably) undeterminable at this point.

It would be helpful to actually be able to determine a DIY way to measure this, and ultimately be able to fine-tune "A" into correct specifications.

 

I remember you saying you shared my braking problem, and just want to let you know that I did raise the LSPV and nothing changed. Not to say it's not better to leave it.

 

Mark the adjustment rod where it is, and move it up in small increments. You can always go back to your mark. Test drive and see how it feels. As long as you don’t lock up the wheels, or they grab and lunge you forward, I think you’ll be ok. I’ve always adjusted them by trial and error.

 

I did share your braking problem till I replaced the booster, my brakes are mucho better but the rear ain’t quite right. Hardly get any oil through them when the kids pumping the brakes. Front is fine….

 

Yeahhhhh….. I ain’t going through all that sh*t…… thanks

 

I have that tool… it works nicely.


But super time consuming

 

Is the weight of the truck on the wheels while bleeding ?

 

Are the rear drums properly adjusted? That’s usually the problem I run into at work when people feel they’re not working very well.

 

Just a regular sized replacement? I think I've heard of larger, yet compatible boosters

 

Not surprising from you.

Care to share the details of that tool? Does it fit into the bleeder valve port? assuming it does, that means it probably has to be bleed once in place, and that is the time-consuming part?

 

Mine was obvious, it started weezing loudly and the braking was big time horrible. I adjusted the arm on the lsv, the little lift bracket was only a 1.5”, got the extra 1/2 via the adjustable rod. Brakes are fine now. My booster must have been slowing failing….

 

I don’t know if it matters, logically it wouldn’t but I’ve heard of stranger things…. It was on the ground

 

As you’d imagine it’s just hook up to bleeders and go… it’s not super difficult, but it’s annoying to use.. they were throwing it out at work. So me being me, I took the opportunity to dumpster dive for it lol.

doing it by feel is how I go most of the time, but with the frame swaps I use the tool. It’s faster since I’m already there
