Hi there,
I have a 2016 SR5 4x4 V6 dual cab, brought brand new and kept pretty much stock accept for a tray back and changed the factory tyres to BFG AT's.
It's done around 65,000kms and done no real hard off roading, just the odd fire trail and bit of beach driving.
In the last 5000kms I've started to notice a shudder in the steering and brake pedal.
It only occurs when you are doing over 100kph on a freeway and brake heavily on a down hill section of road.
I've pulled the front wheels off and inspected the brakes, the disc rotors show no sign of cracks / warping or damage of any sort. The Callipers move freely and the pads and in good condition with over 50% material on them still.
All the suspension and steering joints are solid and have no signs of damage.
I had the front wheels re balanced as one of them looked like it had lost a balancing weight, The tyre shop said they where both out by around 30 grams.
However the shuddering still occurs.
The only thing I can put it down to is that one of the rotors has developed a very slight warp that is not visible to the eye and runs edge to edge all the way through the rotor and only starts to become noticeable to high speed when breaking heavily....
Does any body have any other ideas???
If it is the rotor what is your experience in having it machined?
Do they tend to warp again afterwards?
Is it best to replace the rotors instead? and if so are the factory ones known for these issues? should I replace with an aftermarket rotor?
Cheers.
