Front Brakes Locking Up
Bosch/Bendix HB came with two steel braided lines. One comes off the ps pump to the HB, and then the other goes from HB to steering box. A return line comes off of the HB and splices into the return from the steering box back to the ps pump. Fluid doesn't smell burnt, but it does look a bit...- lance.brown

Front Brakes Locking Up
The HB is made for this particular model truck. Yes the brake pedal does return to its normal position when you remove your foot. I did not change the ps pump. Does a HB upgrade typically need an upgraded ps pump too? I was originally told that the ps pump would be sufficient. I have not...- lance.brown

Front Brakes Locking Up
A few weeks ago, I replaced the vacuum brake booster on my 1999 Tahoe with a Bosch Hydroboost and new MC. Now (very intermittently) the pedal will get very hard and the front brakes will lock up. This has happened twice to me in the last two weeks on my way to work. I pulled over, shut it...- lance.brown

Brake Light Switch - Pin Wire diagram
Thanks! If you find the 1992 connector info, I'll be set. The 1992 connector has a Purple wire, Green wire, Brown wire, and Pink/White wire. I'd like to assume that the purple and brown wires are the same from the 1992 to 1999, but I don't trust GM enough to not check/be sure.- lance.brown

Update You can put a 1992/93 style brake light switch on a 1999 Tahoe. However, it does require a small modification to the steering column bracket to allow room for the older style switch to swing and function properly. As for wiring - the orange wire is the constant hot wire and the white...- lance.brown

The original design vacuum booster had one continuous smooth rod. The new hydrobooster has a split rod that is thread the length of the rod. There is a hexnut that is ~2" long that holds the split rod together. This allows you to "fine tune" the length of the push rod connected to the pedal...- lance.brown

Brake Light Switch - Pin Wire diagram
Back story - I have 1999 Chevy Tahoe. I was tired of the weak brakes, so I upgraded the entire system. Installed a Bosch hydraboost and new mater cylinder to replace the original vacuum booster and master cylinder. Also replaced back drums with discs and new calipers. NOW, the original...- lance.brown
