OK, here's the next report. the 2 products the auto tech instructor loaned me are, CRC De-Squeak spray, technician grade. "spray a light even coating on the friction surface of the rotor." So I did that. It goes on like light paint. The other one is Wynn's Stop Squeak to put on the pads. It's a thin liquid that seems to have very fine particles suspended. About 3-4 drops on each pad, spread it around and let it dry. Then repeat and let it dry at least 15 minutes before reassembly. So I did that. Then I drove slowly around the block a little testing things out. Braking effect was reduced on the first few applications. Then I went and made some moderate stops from 45 to about 10mph. 4 or 5 of those in fairly rapid succession and I could smell the brakes and was just starting to feel the fade on the last stop. (maybe I did too much?) Then gentle drive home, about a mile, maybe 5-7 minutes. Read brake temps with IR gun. Hard to get a good reading through the holes in the wheels, but I took the highest readings. Fronts: 330/360. Rears: 224/197. I have a wheel cylinder replacement coming up and want to check out the shoe shimming that Dennis mentions. I have a feeling the temp difference on the rears is due to the one wheel cylinder pulling back. I let it cool completely and pulled one wheel off and took a look at the pads. They seemed to be glazed again. Put them back and drove on an errand and they seemed fine in terms of noise and pedal effort/effect ratio. When I got home I did the temps again and they were more even left-right than before. Edward |
