i have tryed everything to stop my brakes screaching, ive machined all the discs and all new pads, and they still do it, any suggestions.

Also, do u ppl think a 3.23 gear ratio too high for a 3 speed Auto

Thankz ppl

Do they squeek when yer driving off with no pedal pressure?
If so then id say the pistons have seized. The back ones tend to do this more so then the front. Make sure ure using decent pads too...

I know that there is a product that you canspray onto the back of the pads to try to combat this. I just forget what its called, thats all. Some cases it works, others it may not. May be worth a try??

i have also applied that spray on the back and it still does it

Hmm, have you ever faded the new brake pads?

About the diff, a 3.23 would be fine for acceleration, but personally I would be unable to stand the racket at 100 km/h. The only solution for me is a manual conversion.

Is this a hidden hint?

Well I won't lie - the 5 speed is the best way to go for anyone after a combination of quiet cruising and fast acceleration (which I am). The 4 speed autos can be set up to give a good compromise, but with the 3 speed you can't do much at all.

Ways to stop brake squeal 101:

a) Brake adhesive like the pink goo CRC Stop Squeak (better than the spray on stuff) and use it to put the those anti squeal tin bits that sit under each end of the pad on as well. Usually works and best way to do it.
b) Light scuff of disk with emery paper with a circular motion to deglaze. Should always be done when replacing pads.
c) Cut radial cuts into the pad (ie running from centre of wheel out). Use a hack saw and saw into pad within 2 mm of backing plate (some pads come with this radial cut or a larger central groove already). One cut in centre of pad should do it but two cut equal distance apart is also OK.
d) Chamfer the leading edge (lower short side) of the pads with a chissel or sanding block - ie 45 degree angle taking 1mm to 3 mm off the corner so that pads meet the disk at a 45 degrees rather than 90 (again some pads come this way).
e) Remember all pads make a noise (friction pad again a fast spinning disk) it's just usually at a frequency you can't hear it or at a speed where other noises drown it out. The foregoing tricks change the frequency of the sound and reduce the pad vibration.
