STOP! Well, more like CAN'T GO!
This is what happens when I decided that I was going to do the braking system myself for the tow vehicle. I was installing the Air Force One braking system in my car and I accidentally drilled into the brake booster on the back side. I was trying to mount a small plate right behind the brake pedal on the floorboard (firewall). Because this is such a small car, there isn't much room to mount this thing. As luck would have it, I hit the brake booster on the other side of the firewall.
On my way to work, I turned the Air-con on...well, I do live in Central FL! I noticed that the engine was laboring and revving up quite a bit to keep a steady speed. I made it to a stop to make a turn, and then it all hit....my anti-lock brake light came on, and my brakes were smoking!! I made it to a nearby lot to call for HELP.
I ended up buying the new booster off Amazon and taking it to a local auto-shop to have them fix it. They did a great job in replacing it AND putting my bracket back into place. They bolted from the engine side so I wouldn't be tempted to drill into the new brake booster!
