Need A Rotor Diagnosis (pic inside)

[vintageracer]

Just a thought. We had a fellow racer with Datsun 510 at a Vintage Race that was having what he thought was TV with his rotors. After a thorough complete front suspension evaluation by several fellow racers including myself at the track, the problem was isolated to a loose idler arm. The slight feedback he was getting through the steering wheel and brake pedal was actually the steering arms moving ever so slightly up and down. He replaced the idler arm and problem was solved. He now realizes that HIS "pre race" car preparation must improve!



The owner was the only one who drove the car so his initial diagnosis was based only upon his own personal skill set. When others with more knowledge looked at the problem from a broader perspective of the whole front suspension, the real problem was found.

This may not relate to your problem however it is something to consider!
