Chewing through rotors after tundra brake swap

[biggas]

Hey all, Thanks to everyone for all, and I mean ALL, the info for the tundra brake swap. I pulled calipers off a 2003 Tundra (new pads of course) for my 2000 4Runner a couple of years ago. Since the swap though, I'm still destroying rotors - to the tune of rattling my fillings out after about 9 months.

I've tried el-cheapos, mid-levels, Genuine toyota rotors, and they've all lasted about the same. Didn't machine any of them because I wanted to see if brands or quality (price...) made a difference. Bedded in the pads each time. Tried new pads after the second pair of rotors went. I've just installed my 4th pair of rotors. The only thing I haven't done is gone with a brand new caliper but the pistons seem to be moving fine.

I've also checked and serviced the rear drums to make sure nothing looks wacky back there, but all seems fine.

Has anyone else experienced this?

Just curious, but what kind of pads are you using?

 

[biggas]

Raybestos, run-of-the-mill, nothing fancy.

Napa calipers here, oem rotors and pads. Never had an issue. When you say they are gone you mean they are warped so bad it vibrates your teeth out?

Might be your issue, and that's not the rotors warping perhaps, but pad deposits forming unevenly on the rotors.

What sort of driving do you do? Do you live up in the mountains? If you're riding brakes all the way down a huge hill every day, that'd probably do any sort of brakes in.

You probably have a bad caliper.
My fathers 06 Dbl Cab Tundra just ate a set of rotors after a year or so on new pads and rotors
Its because a caliper went bad. Caused a horrible vibration when stopping.
Has been replaced (calipers and rotors) and no issues

Thanks for the input.
Jay, slight exaggeration, but ya, the vibration is pretty crazy. With fresh rotors there's nithing, so it gradually progresses from perfect to unbearable over a span of about nine months.
Don't think it's the mountains, I don't ride the brakes and I don't hear of anyone else wrecking rotors this fast and consistently around here. Checked the pads and they're wearing pretty evenly so I didn't think it would be that, but I guess that's all that's left. Oh well, guess it's time for a trip to Napa.
Thanks again.

Are both rotors going bad? Or is it just one side? [MENTION=118628]73Duster440[/MENTION] has a good point. Your calipers were used...did you rebuild them? One or both might be bad. If you have a piston inside your caliper that's dragging or isn't releaseing...that would cause your brake pad to continue to engage the rotor...which would cause the excessive wear.

I'd check that out while you're changing brake pads...again!

Let us know how it goes...

i just recently (finally after 7 months of having them) started to rebuild my 05 sequoia 231 calipers and one piston in each of the calipers were pretty stuck..

i would assume if i just threw them in they would still be sticking causing the pistons to not all engage the rotor evenly.....

i would say pull them and rebuild them before replacing....

 

[Brilliant]

Calipers be my guess. take it to a cheap brake place like minkee or midas if you can't sort it

 

[Brique]

If you didn't rebuild the calipers when you got them, I'd definitely try that now. Check out the video [MENTION=8729]Speedy[/MENTION] put on YouTube, it's got the step-by-step and the part number for the rebuild kit is in there, too. OEM rebuild kit is $12 online at midatlantictoyotaparts.com

Sticking calipers, they "move" fine but they aren't retracting the pads from te rotor enough after a stop. This overheats the rotor and causes hot spots which are raised off the surface.

4 sets of rotors should be telling you the rotors are NOT the issue.

 

[biggas]

Consensus points to calipers. Rebuild kit would seem to be the logical place to start. Will report back in 9 months Thanks again.

Just another thought, how are your rears? Well adjusted? If your rears are not well adjusted, then you may be forcing the fronts to do all the braking, and so overheating more. This is what I suspect for mine, since my rotors didn't last as long as they should have either. I mean the tundra brakes should be fine to brake the whole vehicle, but still, you're definitely generating more heat that way.
