dan13 Posted September 8, 2020 Share Posted September 8, 2020 Hi all, I'm recently an owner of a 370z, since purchase the car has had a vibration in the pedal and steering wheel under breaking, the braking gets worse the harder you press the pedal or the faster you are going, I assumed this was an issue to do with the front brakes, uneven wear or something between the discs and hubs. I have just replaced the discs,pads and brakes lines for all new at the front. This has improved the vibration alot and it now doesn't happen at lower speeds but it there is still a vibration in the steering wheel when braking from higher speeds. I'm wondering wether I have just masked the problem with new discs and pads and I'm basically after a few suggestions about what to check next that could cause this. I plan to get the balancing/tracking checked this week just to tick that box and rule it out. Any suggestions or help would be much appreciated.

Jack94 Posted September 8, 2020 Share Posted September 8, 2020 (edited) Sounds like DTV, did you clean the mating face of the hub and measure the run out when you fitted the new discs? Edited September 8, 2020 by Jack94 1 Quote Link to comment Share on other sites More sharing options...
dan13 Posted September 8, 2020 Author Share Posted September 8, 2020 @Jack94. I did, I used a wire brush drill attachment and cleaned up the hub so it was pretty good, to be honest it was pretty good anyway. I was hoping to find a load of rubbish in there.

Jack94 Posted September 8, 2020 Share Posted September 8, 2020 If you've already measured the run out of the hub and it was within tolerance then the next thing I'd check is the disc thickness with a micrometer. Quote Link to comment Share on other sites More sharing options...
dan13 Posted September 8, 2020 Author Share Posted September 8, 2020 As mentioned in OP I have replaced the discs so you'd like to think there is no thickness variation, I will have to try and find somewhere to check the hubs as I don't see an accurate way to test this at home Quote Link to comment Share on other sites More sharing options...
Jack94 Posted September 8, 2020 Share Posted September 8, 2020 (edited) Yeah you'd like to think so but it's worth checking. I thought you said you'd already checked the runout? If you haven't that'd be my first point of call. Edited September 8, 2020 by Jack94 Quote Link to comment Share on other sites More sharing options...
