Sounds like front disc problem (distorted). - or maybe pads.when my car goes to 60 the wheel shakes when braking, the wheel doesny shake any speed under that just above it, what can it be?
is it the brakes?
If the grease isn't perfectly distributed over the discs's surface, you'll get areas of high and low friction and therefore uneven heating. Uneven heating = uneven expansion and warping.I've had this problem on my old Rover Coupe (and Rover 214). Changing the front discs and pads cured the problem but it would come back after about 9 months. My coupe had a split CV gator so grease was probably getting onto the disc... don't know why this warps them though?
Warped discs don't usually cause a vibration in the brake pedal, because the brake pads are moved in opposite directions by the deformity in the disc, resulting in very little change in system pressure. The reason it's always most noticeable in the steering is that when the disc is warped, using the brakes means that the pads will try to force the disc to run straight. The vibration from this is more severe the further you get from the axis of rotation, so it's transmitted into the wheel and from there into the steering, where of course there's a direct mechanical link to your hands.My guess is suspension. An imbalanaced wheel would vibrate as you pass through a speed range whether accelerating or braking. Warped discs would more likely cause a vibrabtion in the brake pedal rather than a steering issue.
Track rod end and wishbones become tensioned under braking so any wear or play will show up. TRE is my chief suspect of the two.
