So rattling on the freeway led me to inspect my brakes today and I have a chip in the edge of my drivers side front brake rotor.

The trucks a 2007 Tundra Double Cab 4x 4.7L. My question is can I get a new rotor and pads and:

1) straight replace old with new and be done with it because of the computer controled brakes will adjust for the difference between rotor thicknesses from left and right?

2) turn the new one down to the same thickness as the passenger rotor and replace with new pads left and right?

3) replace both the right and left side with new pads?

I'm guessing number 2 but wanted some sanity-checking before I start. Please agree or disagree or new ideas..... Thanks.

 

Computer controlled brakes? You mean ABS? if so, Just replace pads and rotors. You'll be fine.

 

Replace pads and both rotors. Always replace brake parts in axle pairs.

 

Wouldn't it be cheaper to turn one new one down to match the passenger side? Truck doesn't know ones new and ones not as long as they are the same thickness.

and the electronic braking system is the Vehicle Stability Control (VSC) and the Traction Control (TRAC) which both of them using the brakes independantly on each wheel.

 

Probably not unless you happen to have the equipment to do the turning, you gotta pay somebody even if you own the shop. Just throw a right and left on it and know you won't have to do it again anytime soon. Barring another freak occurence of course.

 

If you're worried about cost. Replace the one broken rotor and re use your pads. I haven't heard of toyota using sensors on the pads or in the caliper to monitor brake life. Bmw's and mercedes use and grounding switch that once the sensors coating is worn through and grounds through the rotor turns on the service light.
The VSC and TRAC systems have nothing to do with brake life. All they do by computer, apply brakes to keep you from rolling over/loosing control and limit wheel slip when there isn't traction.

for VSC system.

For TRC system

yeah, wasn't trying to say that the VSC or TRAC monitors brake life, just that they apply the brakes to each wheel differently to the conditions and having one new rotor and one worn rotor might not make a difference with that system vise the old school same force applied to each wheel no matter what the conditions. But that's a far off theory...
I was planning buying one since the original passenger side is still way over 50%, and turning it down to match. I'm active duty with access to the base auto hobby shop which will do it for 10 or 15 bucks I think. And new pads. I would reuse the old ones that are only 6mo old but I'm sure the bad rotor side has eaten up the pads....

 

Rotor thickness may not mater so much. I would guess as long as the pads are new for both sides it should be fine. If you notice it pulls to one side or the other then swap in a new rotor to the other side too.

The vsc and trc use vehicle speed, engine load, and other similar sensors to control the amount of braking per wheel till they see the desired behavioral changes *vehicle slows down etc*

 

thats exactly what I was considering but such a "out there" thought to try to replace only one without turning it...... hate for it screw something up even still.

 

Why shorten the life on a new rotor when you can just replace both. By the time you have them both turned you're well in on a new set.
The traction control doesn't know how much the cyilnders are pushed out when you apply the brakes, or it wouldn't work when you wore them down. It just makes sense to replace brakes in pairs so you don't have to monitor sides individually you have equal braking performance on both sides

 

Once some people make up their mind commonsense will never prevail .

pretty much every one said to just replace both rotors and new pads .

which is pretty much standard practice on any brake job.

If one rotor has cracked do you not think it is possible the other one will also.

sometimes people need to learn things the hard way

 

Never replace just one side.

And turning a new rotor down is nonsense. Just get two new rotors, new pads, and be done with it. You will spend more money and time screwing around turning one down and trying to find an exact thickness than you would just replacing them.

Btw, if you turn one, you have to turn the other. So now you are paying to have two turned down. Doesn't make any sense to me just to save a few dollars.
