Hey everyone, I'm looking for some input. I have a 2001 4runner Limited with 136000 miles. As you all know the brakes on these things could be a lot better. I'm thinking about doing the 231mm Tundra brake upgrade. I was wondering if there is that big of a difference in pedal feel and stopping distance, also has anyone changed the master cylinder/booster with this upgrade. I have read in a few forums to get the complete benefit this should be done too. Any advice or guidance will be appreciated. Thanks :frog:
