Braking when going over 60mph my steering wheel vibrates, I changed the front brakes and rotors and it is still doing it. Any suggestions.

 

Tires?

 

... were the pads properly bedded after the pads and rotors were replaced ?

 

I will say the hubs have rust and they new rotors are not seated properly or tires issue, check if they are out of balance or are requiring an abnormal weight to balance them.

Also give a quick check to the tie rod ends check if there is any play when rocking left o right when jackin the car or tilting up and down position.

 

If all parts were properly installed, proper bedding would have no impact when new. I agree that proper bedding is very important, but brakes will not be affected by proper bedding when new. Bedding only comes into play as the brakes age.

 

how many miles.....around 100K could be tie rods/ball joints worn. Might be tires...good balancer can figure tires out.

 

Forgot to ask. When did the vibration start?

A tire centric problem manifests at speed, while a brake centric problem is more pedal application.

 

... improper bed-in can cause glazing which can cause rotational brake grabbing (pulsing) which can cause wheel shake that transmits to the steering wheel ...

 

perhaps you did not read what I wrote. Yes, those things can happen, but it does NOT happen immediately after you install the new brakes. The OP just did the brakes, The brakes do not "glaze" immediately..it happens over time.. That is what I wrote.

Brake modulation seldom causes shakes on the steering wheel. The first clue of brake problems is felt on the brake pedal (or, when you crash into the car ahead of you...)

 

^ ... OP did not say how soon after the brake job this again occurred ... yes, glazing can happen very soon after a brake job if proper bed-in did not immediately occur ... babying new pads / rotors is not a good thing ...

 

I dont quite agree with this statement as Toyota for their factory pads and rotors actually mentions taking it easy/ "babying" for the first hundreds of miles to help thing settle into place. While you might argue that its a new car, and parameters are different, but a brake replacement usually have new rotors, pads, service of hardware and general check of the brake system.

I know EBC and Stoptech warn of possible glazing if not bed in properly, but most other mfgs like Raybestos and Brembo dont have specific instructions for their brake parts.

 

What year is your GX and how many miles? Is it possible you have a seized caliper piston? This happened with my 4Runner and caused exactly what you are describing. I would feel vibration when braking at higher speeds. I replaced the calipers and it completely resolved it.
