i have a problem.... - Toyota Nation Forum : Toyota Car and Truck Forums

lalojamesliz · 03-13-2008, 11:17 AM

so i finally got some rims and while i was washing my car i thought.... hmmm now that you can see my calipers i should clean them.... so i got a sand blaster and......yeah right! i got a few towels and Q-tips and started to wipe. the rear calipers look nice but the front.... well they look better. i even cleaned the back of the exposed brake pads (i didnt think if it might be a bad idea

) so now i have a squeek squeek squeek only on my front left wheel and it seems to be on one spot of the wheel only after a few minutes of driving that will not go away until i park it for a while. i was thinking of taking taking the wheel off and starring at it for a few hours because i wont know how to fix this

anyone ever have this problem? can somebody help me. so, this started when i washed my car and cleaned the calipers with a towel now i have a squeek on a certain part of my front left wheel only and my front rotors were turned and new pads installed no more than 2k miles ago at my toyota dealership because the were warped and i have a 07 V6 with 28,9xx miles as of now oh yeah im usually easy on the brakes. i do not have any vibration when i apply the brakes.

Try washing the rotor with water and detergent.

Also go to Auto Zone or what ever parts store you have in your area. Ask for some break pad grease it will be i little packet of goo. Smear that right on the rotor metal surface and it noise should be gone. If it is one wheel be sure the squeel tab is not what is making the noise. Its a little metal clip that contacts the rotor when the pad is getting worn out.

DO NOT APPLY ANY TYPE OF GREASE ON THE ROTOR. The Anti Squeel lubricant is for the brake pad backing.

yeah that'll jsut lubricate it making it harder to stop. the grease i s for the back of the pads.

That's the DUMBEST thing I've EVER seen posted for tech advice. You NEVER put grease on a brake rotor (it's spelled brAKE). You advice could easily get someone KILLED. I know that you hate it if someone disagrees with you but that kind of stupidity can have serious consequences. Wise up and know your own limitations. You claim to have all this racing experience but any fool would know better than to put grease on a brake rotor.

To the OP: You probably dislodged some dirt or debris that got into the pads. Also, a small bit of surface rust probably developed on the rotors. The first think that I would do is nothing. It should go away after driving for a while. If it doesn't post again. Someone that actually knows what they're talking about will get you going in the right direction.

my rotors did get a little rusted... ill just take off the wheel scuff up the rotor very little along with the pads and ill report what happens. but thanks guys

this started on this monday so i already tried your advice. great minds think alike

Use 120-150 grit sand paper and a sanding block. Then detergent and water to wash off any debris. Dry them off towel.

TRD VVTi · 03-13-2008, 05:51 PM

I've used a pressure washer and sprayed the rotor so that the water went between the pads and rotors with success before.

If that fails, I would recommend removing the pads and lightly sanding them and the rotor contact areas do get rid of any glazing or debris. Make sure that all the anti rattle clips are secure and the wear indicator isn't touching the rotor.

trd, you crack me up....

as for the o.p. the brake pad grease is a valid suggestion...(when you buy brake pads sometimes it comes with it... so it does serve a purpose...but definitely not on the rotor... lol...) also you might want to try putting it on the little metal clamp thing that holds the brake pad... it can get loose causing the pad to get stuck causing the pad to constantly rub on the rotor etc... causing squeaking....(this happened on my 99)... i dunno about sanding the rotor... uneven sanding, wouldn't that cause the surface to be uneven, causing premature warping?? normal driving should get off any moderate surface rust...

but personally, if i got it done at the dealership, i would drive it right back and ask them to fix it.... since they did the initial job, i'm sure they will recheck everything and make sure everything is properly greased etc for free...

Grease should NEVER be put on the brake pads. Grease is for the caliper slides.

I doubt the the OP is having a problem with the anti-rattle clips or the shims as he didn't remove the caliper or the brake pads.

Lightly sanding the pads and the rotors to deglaze and clean them will not cause any irregularities that will affect performance.

Additionally, I've actually seen a pebble get lodged against the rotor and backing plate once and between the pad and rotor once that caused the same concern.

thanks for clarifying.... if i caused any confusion... i did mean on the caliper side... i just referred to the whole brake pad and backing as "brake pad" ... and as mentioned earlier you do not want to put grease on the rotors themselves and or anything that will cause grease to get on the rotor via transfer... thus the grease should be on caliper side always... not rotor side.... again if i caused any confusion my bad... lol...

as for the shims and anti rattle clips, true he didn't take the caliper apart.... just additional things to trouble shoot, and if you are taking apart the caliper to lightly sand the brake pads, you might as well take the extra 2 seconds and make sure everything is greased......

another question, if he sprayed water on it, when the car has been recently driven, is it possible the extreme change in temperature and metal shrinking, could cause a crack in the brake pad (rotor side actual brake pad) causing squeaking?

TRD VVTi · 03-13-2008, 06:52 PM

I doubt that water spray caused any damage. If that were the case, we couldn't drive through puddles of water without have brake problems.

most puddles are fairly shallow, and wouldn't reach up to the brake caliper no?
to reach the caliper we are talking at least 7-8 inch deep puddle?? driving in the rain wouldn't cause complete submersion like spraying water directly on the rotor....
also when driving the force of the tire of the car would cause the puddle to separate unless going through the puddle very very slowly... also wouldn't extreme temperature changes cause potential warping of the rotor??

again to clarify, i'm no expert, but i have heard these things as urban legend kind of thing... the physics behind it make sense, i.e the rapid heating and cooling of metals etc... so a definite answer would be nice... lol...
thanks for the quick response....
