OP: what brand rotors/pads have you been using?

I always use Toyota brake parts and have never had issues with warping. Once I put Jon-OEM rotors/pads on my old Sequoia and had terrible vibrations on my first trip through the mountains. Switched back to OEM and never had an issue. I think OEM parts are made to tighter tolerances for things like run out, composition, etc

 

Do you use the parking brake a lot? Are you really melting through the brakes like a new york taxi driver?

No that's not normal.

 

Your post implies that you are doing the work yourself and own/have-access-to a lath/brake skimmer. How many thous did you have to skim off the rotors? Before skimming, I imagine you probably checked the thickness with a caliper to measure any difference in thickness as well as with a dial caliper for run out, how much were they out?

 

Lots of great ideas from others.
I only like to add that I use oem rotors/pads and torque my rims properly and don't use my brakes hard if I don't need to and this seems to help.

People have good luck with different brands of pads/rotors but it seems todays rotors are much lighter
these days compared to cars of equal weight many years ago when it was popular to resurface them.

 

[QUOTE=cb1111;10696020]It is unlikely that the rotors are actually warping. Warping a rotor on a street driven car (not on a race track) is next to impossible.

This is not true. Rotors can be warped quite easily due to operator error or if you are someone that drives your car like you stole it and brake like it too.

 

Also check your calipers. If the caliper cylinders are sticky, you'll build up excessive heat.

As Margate330 mentioned above, improper lug nut torque could be a factor.

 

Warped rotors result from excessive heat. Excessive heat results from riding your brakes. Make sure that you are NOT a left foot braker as many left-footers tend to let their left foot rest on the brake pedal. Following too close also results in excessive brake use as does riding your brakes down long hills (where you should shift to a lower gear instead.)

 

Your cart quote is $100 high. You don't need 2 sets of each brake pad "kits". 1 kit covers the entire front or rear. But nice to have all P/Ns in one place. 👍

 

I was wondering when someone was going to notice that.

 

anyone tried stainless steel brake lines? did they help with the pedal travel?

 

Thanks for finding my mistake here.

Speak up then

 

Sorry for the late reply! TRD Front: PTR09-89111 TRD Rear: PTR09-89110. Been working great for several months!

 

Typically helps firm the pedal feel. These should always be a last resort, especially for our application. A fresh bleed with new fluid will make a more noticeable difference than stainless lines.

 

Hello, I had an issue with my brakes. At the end of February, 25th of 2020 to be exact, i went to a local Lexus to do my maintenance and i needed to replace my brakes. They replaced my front and rear brakes as well as rotors. During quarantine i wasn't driving much, the car spent most of the time parked. About 2-3 weeks ago i noticed that when im going 40mph and up and then start to brake my steering wheel is jerking left and right and its tough to hold the car straight. I looked up online and most of the pointers were to bad rotors. I went to the dealer since everything is still under warranty, its only been 4 months and i drove about 2500 miles ONLY since then so failing brakes is strange. At the dealer they of course didnt want to believe me until we got on a highway and test drove the car, even then they were blaming it on a sway bar failure and wanted to charge me an arm and the leg for it yet it didnt fall under any of the red flags for a bad sway bar. So after about 6 hours of arguing back and forth with them they took the wheels off and replaced my front rotors and brake pads, the car is ideal after, not even tiny vibrations when i brake. I went to a random car shop on my way home, they looked at the sway bar and said its is good shape, my question is have anyone had their brakes go bad so fast on a GX, it was my 1st time replacing brakes, ive never had an issue, usually ( on my ES and both RX ) they would last me about 2 years with a lot of daily driving. Are GX brakes weaker, should i be looking at upgrading entire brake system from stock, am i doing something wrong on my end? GX is well-maintained, im not a crazy driver so they shouldn't be failing / wearing off so fast or is it possible Lexus just messed up their job to begin with? TIA

 

It's very important to bed the brakes after replacement. If this is not done properly it can lead to deposits being left on the rotor from the pads and causes this type of shaking during high speed braking. In other words, the rotors themselves are not warping but the pads leave deposits on the surface of the rotor causing the same effect. This sounds like what happened. Brake issues are not common on the GX.
