Broken Bolts.
In the past month I have broken a caliper bracket bolt, 4 dust shield bolts and I am now finding that some of my front wheel studs are getting harder to torque consistently.
Background:
- Had car since June 2012
- Winter driving
- Approx. 2 track days per month in summer
- HP+ on fronts, stock calipers.
- Driving instructor, typically lap faster 4-10 secs faster than others in same car (2:30 typical lap)
- Light and smooth on the brakes at the track
Could there be this much heat being generated that these bolts are getting weakened by the heat?
I am working on completing the brake cooling this weekend regardless (ducts routed through to centre of rotor backside) and this will obviously add much cooling, but curious if anyone has had similar issues with breakage?
I used to run a Miata in Time Attack years ago and just pounded that car every weekend, and never had issues of this kind. |
I'd recommend you use a torque wrench, and use anti-seize on the wheel studs. Make sure the other bolts are also clean, and if you're changing things regularly, also use anti-seize, and make sure to re-torque them after a session of getting hot.
Most anti-seize has a 1500F+ heat tolerance; the stuff we ship with our lug nuts is 2000F+.
