on the contrary my Toyota squealed like a pig when it had pads with shims on it, then I took out the shim, guess what, no more squeal.

Toyota is a bit on the Masochistic side, I tell ya.

The 90 300e was running worse and worse. Often it would stumble at start up, be OK until fully warm and then would constantly die unless the RPMs were kept high.

I searched these threads, I changed too many parts to admit, I tested, I checked, I replaced more parts (plugs, rotor, caps, E-everything) .... still the same problem.

With great humility I took it to my local indie. I waited for "the list" and how much...... I brought a book to help me through the long wait in the customer waiting area.

Within minutes the car was out of the shop and running like new. Bad coil. But everyone said "those coils never fail ......".

Mine did.

try avoiding the use of non original or non OEM brake pads, you'll have less chance of sufferring the squell.
