Rear brake question.

Well im workin on layyin my truck out.. started gettin the back half cleaned up to start nothcing. And i got a couple questions on the rear brake setup.. It seems to be alot different than any that ive worked on before. im used to chevys, which have 1 E-brake cable, And 1 hydraulic line, Tee'd off into each rear wheel.. On this truck, t here 2 lines, That seem to run into some type of proportioning valve, And teed off into a single brake hose, Then teed off to each drum. Now theres also some fuckin rod goin from my frame to my axle. almost like a panhard bar, But its like thin ass metal. Wondering what it does, and weather or not i need it..

Also what are you guys doing with the rear brake lines after you notch the frame.. Could i just Tee the 2 rear lines off into a brake hose, and connect it to the T fittign on the axle that goes to the drums?

hers a pic of what im talkin about.

Check out the suspension system. We've covered how to eliminate the LSPV.

alright cool. i searched and couldnt find anything. didnt know what the hell it was.. searched lsvp and found it.. Thanks.

Search for perportioning valves


SETH AND I have both made post on two different ways to bypass the LSPV

you can do it their way or just get another axle tee like the one on your axle now. mount it on the notch. works fine. others will nay-say, but i've learned thru personal experience(three of em) that this will work fine. daily driven, on the interstate, under load, ridin 20's, in the snow(what little a yota can do in the snow) and it works perfect.

oh damn! Mine is the first one that I've ever seen like that and then you got one too......sucks huh? FYI though....that little bar thats attached to your axle is what adjusts that proportioning valve. The more your axle travels up the more rear brake is applied. Example....If you have a heavy load the rear is gonna squat because of the weight and in turn it transfers more of the braking force to the rear.....really simple.

Thats why its called an LSPV (Load Sensing Proportioning Valve).

I do disagree with running a T on the rear axle. Especially with discs. When I first installed mine I opened my proportioning valve all the way to increase the flow and make it bleed the system faster since it was dry. I forgot to adjust it after, and the brakes would lock up in the back pretty easily. I say don't be ghetto and do it right...

my LSPV was moved behind my notch, and it was leaking brake fluid recently, so i had to replace it. do you think that since the bar that connects to the axle moves alot more since my truck is bagged, that it could have caused the LSPV to leak? because i have been told that it is rare to have any problems with that valve.

all three i've done were drum. no lock up.

can anyone help me with this?
