Unsually brake situation

Unsually brake situation

Alright so i got a new brake setup, i got the Powerslot rotors and the Hawk HPS brake pads installed. First like 500 miles were ok, but then i started noticing very recently that the breaks are squeeling under light braking, and it goes away under hard braking, the squeeling is actualyl really loud, so i'm not sure whats wrong wit.... i know that these type of brakes do have a tendency to squeel alot, but i was told these barely do if any....

Next probably i noticed that when i look at the rotors they have like 2 grooves scrachted into them in a circular motion like a metal peice just scratching into the rotor itself, but everything is new....

And next i noticed that sometimes i can hear the brakes like giving a type of grinding noise like my old rotors and pads were doing, but they were warped from excessive heat supposedly, they were very glossy and had a bluish tint to them or so the shop said...., not sure how i can tell if its warped or not, but i think its happening again, and i don't drive so aggresevily, and i don't ride my breaks, and even if i do break little more then usually, these rotors should stop the whole warping thing..... i have inspection soon and i cannot afford not passing again cause of brakes, cause it seems like every inspection, something is wrong wit my brakes.......its insane!

damn it!, well how bout the rotors, i'm more then sure toyota will try to sell me their brakes, if i buy them, wat bout the rotors....?

im worried that scratched surface though, i heard these cant be resurfaced.... hmmm i wonder how much toyota will charge me for the new pads

I've got the exact same problem, same setup w/power slots + hawk HPS. The noise is only on my driver side though...

I had my brakes inspected and my calipers replaced cuz it felt like one side was sticking...

but the problem still persists..

Did they grease the calipers?

That reminds me..I need to do that.

yes you should grease the calipers and apply the silicone-with-something-else stuff to the back of the pads. you can also try swapping in an anti-squal spring from a 93-97 model. also check your torques with a torque wrench.

just pop out the pads and clean them along with the surface where the piston meets the pads with a wire brush. Brake squeel to a extent is normal with higher performance brakes.. my setup squeel when its cold but goes away after its warmed up a little

right when i got the pads, the stopping power was amazing, like especialyl when i'm driving around on the highway or what not, like as i start breaking hard its not that good, but as i slow down and the pads really heat up they really start gripping, a whole lot better then OEM

ya that could be true, on my moms 05 rolla the brakes feel really good, but that could be also to a diff design and setup, so its hard to compare...

E why dont you like aftermarket rotors or pads, they are great.

I have had my car for 4 years and in the first 2 years I went throu 3 set of rotors and pads then I went to Brembo's which are cross drilled and slotted with Ceramic pads and I have not had to change anything in 2 years, they are great.

Ceramic pads will work as well if not better than OEM.

Yes I can be hard on my brakes, and I know it but thats me.

With braking power I have noticed better braking with this setup then with a new stock setup.

...3 sets of rotors and pads in 2 years? That's being a little generous on the brakes.

I can stop my truck on a dime...running stock rotors in the front, drums on the rear. The rear shoes have 62k and some change...the front pads I just changed out around 50k miles.

Also...alot of times disc squeeling is more often than not due to dust build-up. Brake Cleaner takes care of it real quick. And if you are running rotors that have alot of mileage on them...there is a product actually called Disc Brake Quiet.

...also...it's just something we all have to deal with...
-- Disc Brakes Squeak --

Discs on my bike squeal like a mother unless I clean 'em every week or so.

cross drilled - yes I agree, both pointless and a liability to the structual integrity of the rotor.
slotted - that can be useful in street drive applicaton because it's main objective is to evacuate brake dust from between the pads and rotors.

I dont think there are any problems with upgrading pads to a compound with a bit more bite unless you are one of those guys who cant take a lil brake squeel and a bit more brake dust to clean.

Thanks for the explation E, and yes I am a little hard on the brakes, cause what I was doing with the stock was warping the piss out of the rotors, and will my curretn setup I cannt do it, yea I agree its a little overkill on a street car but if it helps my wallet recoup I will do it.

Reason why I was going throu tires like crazy was the fact that both of my front lower controls are bent just slightly and it took awhile to find the problem cause some of the alignment shops here have crappy techs, and Toyota wanted a 2 arms and 2 legs for an alignement on a lowered car.

really? i'm about do inspection and i want them to do an alighment since firestone couldn't do one the right way, i figured since its trd springs and the kyb struts it should be a problem and should be able to do it for same price

Yea most places dont have the right tools or dont want to do a alighnment on a lowered car. I ended up getting my alighnment done at NTB (National Tire and Battery) for about 100 bucks.

I was having the problem (albeit the noise wasn't as horrendous) with my OEM pads and rotors - so I replaced them along with the calipers. Yes, the pins were greased, and we've already tried that silicone lube, and cleaned the brakes, etc. etc.

I have Brembo cross-drilled and slotted rotors with Hawk HPS. I hate the pads!!!!! No note-worthy extra bite that I've heard about and ridiculous amounts of brake dust. I got robbed. Fortunately, no noise yet with 5,000 miles on them.

would toyota charge me extra for alighnment with my trd springs and the kyb gr2 struts, its supposedlty enough of a drop for it to not have issues wit alighnment

a chain store named wheel works ripped my friend off on his alignment.. should be 60bucks but charged 100 cause he had S techs and tokicos and they tacked on a "modify suspension charge." Total bs, all suspension pieces were factory spec, and the alignment procedure is no different from if it had stock suspension.

I get my alignment done at a race shop and they charge the same price for a spec'ed alignment on my fully adjustable suspension.

Yea there are 2 alighnment shops in Newark that will work on lowered cars. NTB and Bear alighment, NTB wants 100 and Bear wanted 140.

I got my alignment done at tire kingdom after I lowered the car, but before I put on the new struts. They even gave me the how many ever mile warranty. I went in after I installed the new struts and gave them a line about the car pulling the the right and the re-did the alignment for free under the warranty. Not once on either visit did they say anything about the car being lowered. It was $70.

town fair tire. $70. no questions asked about the lowering. just mentioned if i had a spec sheet. They also sell the azenis rt-215s. $57 for 15" size
