I haven't driven my truck since the end of last winter.....at that time I noticed I was loosing brake fluid but I couldn't find any leaks.....I didn't have any time to take a look any farther since I had other things to do......I got it goin yesterday and it has absolutely no fluid in it and no puddles under it or on any part of the truck........I was wondering if it could maybe be the shaft off th back of the peddle that goes into the booster? I was thinking maybe it's leaking in to my carpet and that's why I don't see any fluid.......I don't know I usually can figure out most of these kind of problems but this is just driving me nuts and lol I'm ready to just replace everything......then all I need to figure out is the damn tail light wiring if anyone can point me in the direction of a good schematic.........oh yeah it's a "89 22re 5 spd pu

 

have you tried unbolting the master cyl, to see if the back seal is bad.it might be collecting fluid in the brake booster. you might try autozones free online manuals for the wiring problem.

 

I had an 86 that would leak from the master cylinder on the interior side of the firewall. I noticed it becuase brake fluid would run down my brake pedal and things got real slick!

 

haha my reservoir leaks but you cant tell unless you look REAL close.. then you can see a lil wetness but over like 3 months if i dont fill it it leaks all the way out,,

 

Yeah I'll have to check that out.........



I think I gotta totally open up the wiring harness back there......I have a all-pro bed I put on there a few years back and have led's in place of the original tail lights......so i'm thinking it might be a diode or maybe something like that.

 

No I mean I push on the peddle and I have no brake fluid..........it drains so fast it's crazy
