Hey All,
I am just starting to work on my car myself.
I recently changed rotors and pads on the rear of my 2007 TL and I have some vibrations when I go over 45/50. It doesn't happen all the time and once I come to a complete stop and go again it doesn't do it again for a couple miles.
I am going to change the fronts this week and do a brake fluid flush at that time.
Both rear calipers have been replaced in the last 2/3 years.
As you can see in one of the photos the rotor has some red or pink on it.
Both wheels seem to have a little resistance when i turn the wheels off the ground. And has a little like whoosh sound when turning
They are the stock rims and lug nuts. Torque to 80ft.
The car sat for like a week while i was out of town. Once i changed the brakes when i got back the vibration started.
it only does it sometomes and once it stsrts vibrating it does it until i come to a complete stop.
If im going under 45 or so it doesn't vibrate when i stop.
BROlando, the rotor that is discolored was a little difficult to get off and on. Once I release the brake the car moves freely without me pressing the gas.
The pads look normal.
It shakes regardless of braking.
Once I pull out of my neighborhood toward the highway the speed limit increases so it drives normal up to like 45/50mph. Once I hit that it vibrates and shakes. After it does that I pull over and turn around, once I do that it stops doing it until I hit the that speed again so I pull over come to complete stop and it is good until that 45/50 speed.
It must have been something I did because for a car with 260k miles it drove excellent up until I changed the brakes.
See the "star" shaped adjuster wheel? You dial that down until you can JUST barely slip the rotor on easily.
Remove the rubber inspection hole cap that is in the rotor hat. Turn the inspection hole so you can reach the star adjuster with a flathead screwdriver.
Then, dial the adjuster tighter in small increments until you feel some drag on the rotor.
Then dial it back down in tiny increments until you feel no drag.
Done.
**while you have the rotor off, before you do any of the above....make sure the sliders and spreaders are clean. Clean them with brake cleaner and a brush. Then lube them up. You want to use MoS2 lube. But...if you don't have that, then some caliper lube should work.
