My old TD7E with about 4100 hours on it has noisy brakes after a couple hours of running in high temps(Texas). It never did this in spring or winter. When de-celerating to switch fwd or rev, the brakes will "groan" . Anyone have any idea? Are they wet brakes or dry? Thanks.
I should have said, when de celerating and applying the brake to bring to complete stop to shift from fwd to rev is when they groan.
