Spring chirping sound from brakes

[cpunk]

Hey dudes!

I bought myself a new Celica, well for me it's newer than my 1.6 EFI. So I got this Celica GT4 from 1994 (but it's the 5-gen) possibly the last one out from the factory. It's in awesome shape but it has some weird small fails.

Everything is fixed now but I still have a "chirping" sound when I brake slow, the brakes are changed all the way down to the discs and pads. The sound only comes when I brake slow in low speeds but in high ass panic brakes nothing happens. Anyway the sound is electric like the ABS is trying to make some difference in the breaking but "chirps" and pushes my foot a bit like an annoying vibration

No one knows what the poop it is;
* the ABS warning light is not responding
* checked the ABS holders and the attached stuff to it
* ECU shows nothing
* Fluids are changed
* Pressure is checked
* Brake pad is checked

What is this?

Anyway I have a small leakage at the back diff axle which needs to be changed but it shouldn't have anything to do with the brakes...

Nice Trac. Do you have wheel adapters on your car, or smaller fenders? THose 7th gen rims look more flush on your ride than other 5th gens ive seen rocking them.

did you change the rear brakes as well?

I have spacers on the back, but I had these sounds and vibrations way before even starting doing anything to the car... Trust me I checked all the visible errors, and had 2 guys looking at it at 2 different workshops. They can't find the problem...

The works... The only thing left original is the "ok" don't know the english term, where the break pads are installed...

Oh I just realized that you where giving me credz =p

Yeah well it's spacers on the back and 16" rims with over sized tires 215/65, it scratches a bit on the fenders at the back when I rock the car but that's gonna go away when I have my new D2 coilovers next year...

No adapters like those plastic circles or anything, they fit right in.
Check it (I have to repaint and fix them up later though):

What kind of brake pads did you put on? Some of the pads have to have stop squeal on them until they brake in and if you don't use it they will have a bit of a squeal to them and the vibration that you are feeling if you have these kind off pad's on is them grabbing on the rotor's. The part's shop you got your pad's should have told you this. Or your brake calipers are sticking on soft braking and need to be replaced.

The thing is that this chirping was there way before any changes was made to the breaks. And it's electrical as I said before, it only makes this sound when I break slow like; when parking or before a traffic light.

The parts are fine, 2 guys checked it out and looked for mechanical problems and couldn't find anything.

We found the problem, it seams that one of the "sensors" in one of the wheels are off, it's a electrical problem because the values from the ECU are false. Nothing that one needs to fix but it's still annoying. Both Toyota, the car controller guys and the mechanic point towards the sensor being the problem, because everything else is changed and checked...

nice you solved your own problem, always a good feeling.
