Had brake rotors turned at 30k + miles. Getting shutter when braking. Wonder if anyone else has brake issues...I think 30k miles is a little soon for that.

 

not a big issue, the rotors are warped and need to be resurfaced.

 

what was the reason you have the rotors turned at 30K? Were they warped? Did you also have your brake pads replaced?

30K seems a little early for front pads on an RX.

Also I would never have rotors turned on any modern vehicle since the tolerances are so tight there is not much extra material to work with and the thinner the disc the more likely it is to warp.

If the rotors are true and there are no deep gouges, I will just hit the surface with 120 grit on an orbital sander.

Also lug nut torque and sequence will affect the rotors if not done properly.

 

Yes, rotors were warped. Pads are still good, therefore had the rotors turned alone. Lug nut torque was even and within spec all around. Didn't go through any water after braking so don't think rapid heating/cooling an issue. Not heard good things about Japanese SUV brakes in general...seems underdesigned. My GMC changed first set pads and turned rotors at 1ook miles. Thanks for info.

 

Are you holding the brakes on going downhill?
These SUV's have great braking power, and are not under-designed (i suppose you meant under-sized), I have no idea where you heard that. If anything GM needs to learn from Japanese Auto Makers.

 

I have mixed results from the RXs brakes. This is coming from a 2nd gen RX. I have to change the brake pads pretty frequently. At 110, 000 miles, I have had them changed at the dealership at least 3 times if not 4. The car doesnt seem to want to stop on a downhill, and I get a lot of creaking and growning from them/and or from the suspension. Of course, I live in a city famous for their hills and I go on them every day, which might be responsible for the quick wear.

Either way, the brakes could be bigger...the RX is such a heavy car, when I see sport sedans with larger discs.

 

Holy cow hypervish, how do you get cars to last that long in the snow belt? (looked at your sig)

Yes, undersized is what I meant, but that implies underdesigned. When the Toyota Sequoia's first came out, two of our friends ended up changing their brakes near 10-15k miles. Toyota's first foray into full size SUV with little car brakes....I've never forgotten that one. No brake holding either down hills or otherwise on our 350RX. I'm dubious about towing anything with this RX...I guess that's why we have our GM truck.

RXSF, yes, our 05RX had brakes replaced at about 40k intervals, but not so much any rotor issues. At least the pads are doing better on this gen RX.

 

how are your tires hold up if you have the 19" Wheels? going to get 40k + miles before a change?

 

We have 18" Dunlops. THey look like they will easily last 40k+ miles. have 8/32" tread remaining.
