How were your brakes and their performance before you opted to install the brake kit? Could you lock them up on pavement at speed with ease? How did they react in a panic stop? When is the last time you did a full fluid flush as part of your brake system maintenance?
None of those are pointing fingers in hopes of rendering some sort of judgement. If you are different than most all the other folks I deal with daily, then good on ya and I'll be very pleasantly surprised.
But, most folks fully ignore their brakes as long as they do something when they mash on the pedal. Then I get the phone call or email wanting to know if they should do pads or a brake kit. My question is always the same, how close to lock up are you now? The answer is always the same, no idea. Well go find out and get back to me so we at least have some basis to continue the discussion.
