anyways im tired of hearing my brakes squeeling and ish so im gonn upgrade to some type of performance brakes. Not sure what I should get, wanting some drilled / slotted brakes and maybe new capliers? where should I start, searching didnt help much.

do the ST / GT / GTS / ALLTRAC all fit the same size rotors? doubt it but which are interchangeable?

Also how are the rotors on eBay if anyone has bought them before, they seem to be coo and not to pricey (under $150 for 2 fronts) btw I have rear drum....

On slotted/cross-drilling -- bad!

Rotor compatability depends on the year and trim of your car. If you don't have the calipers and brackets to match a certain size rotor, it won't work. E.g. 90 GT cannot use 92 GT/GTS front rotors.

I guess ill just buy these and find some capilers? http://www.nopionline.com/nopistore/dsp_pa...20Celica%201991

I have no idea what you mean by "so basically theres no performance needed with the brakes?"

Subtle hint was missed: what is your current setup? Since it's a 90-91 coupe (I can guess that from the pic), I can't tell whether you have drums or discs in the back -- some GTs came with rear discs.

Brake squeal isn't the result of small brakes. It's either a lack of proper lubrication of the sliders (caliper could be seized), lack of grease on the shoe sliding points, insufficient shims (some models use three on the front caliper, four on the back), failure to apply brake grease to the inner (piston-side) shims on front or rears, missing pad supports or worn out friction material on pads or shoes.

If you've got everything properly greased and installed and your rotors and pads are in good condition, you shouldn't be getting a lot of noise. If you are, try upgrading your pads for noise suppression.

pads are new... brake squal isnt the result of small brakes? common sense i guess, but thanks for the info btw drum in the back

most parts between celicas r interchangable. example i have a 90 celica gt. my brake rotors warped i got then machined. then they warped again in a matter of like 3-4 weeks. so i opted on getting bigger rotors, i bought a wrecked 92 celica gt and pulled the rotor and bracket off of it and put it on mine, and no i didn't change calipers, i used the same ones that were on my car. now my brake problem is solved and it's been 9 months without a problem.

you can also buy toyota camry rotor, they will fit and cost about $25
