    Is the Tundra brake booster direct bolt on?
    Are you running bigger brakes?
    How is the pedal feel?

    My XRunner has front BBK 360mm and Rear Disk Conversion 345mm from Performance Brakes Unlimited.
    Pedal feels great.

    The tundra master cylinder is a disc/disc master. Did you have to run a proportioning valve? I'm curious as to how that is working out. Did it directly bolt on?

    Hi there;
    No proportioning valve required, The ABS pump, ECU along with the ABS sensor on each wheel monitors speed and movement to prevent any brake locking on the brake system, I have been using this set up for almost a year, no issues.
    The Booster will bolt on into the fire wall, everything else need a custom hardware kit available at Performance Brakes Unlimited.
    Also If there's anybody around Houston that would like to test my Truck (Brakes), just let me know we can set up a day.
    Thanks

    I live in Fort Worth I may take you up on that offer of testing them. The kit looks awesome. It will definitely be going on the list of mods in the near future. One last question, do any of the sensors on the master cylinder cause any of the daah lights to light up? I'm guessing they match up perfectly.

    Not a bad deal. A proportioning valve would be needed if keeping drum brakes in the rear.

    More info about ABS.....A standard Anti-lock Braking System uses four wheel speed sensors, a hydraulic pump, four hydraulic valves (assuming it is a 4 channel setup), and a controller. The controller in the ABS system monitors the speed of each wheel using the wheel speed sensors, which are usually hall effect sensors. If the controller sees that one wheel is decelerating at a rate that couldn't possibly correspond to the vehicle's rate of deceleration, it actuates the hydraulic valve in that wheel's brake line to reduce the brake pressure applied to that wheel. This allows the wheel to turn faster. Once the wheel is back up to speed, it uses the pump to introduce the pressure back into that brake line, applying that brake again. When the controller sees rapid deceleration again, it activates the valve and the cycle repeats about 15 times per second. This happens the same on Disk/Drum and/or Disk/Disk.

    I'm only worried about the master locking up the rear brakes before the front. I haven't converted to disc in the rear yet. Drums work a little differently so my guess is that a proportioning valve is needed if keeping drums

    Brakes are the first mod i'm looking to do on my XR. I was looking at the Stoptech 6 pots but this might be better as its using OEM parts. I might as well do the front/rear disk conversions and the booster all at once.

    I'm focusing on this too. I've already got the tundra front brakes. They stop great just need that little extra pedal feel from a bigger master cylinder
