Re: Return of Sienna Squeaking Brakes + Thump...
Here I thought I actually penned an entire note without misspelling
"brake" at least once (I did it again). Thank you everyone for your
comments. I have learned my lesson the hard way, and I will take it to

experienced. In a couple of weeks I'm going to be completely replacing
the brakes front and back on my '88 Toyota Pick-Up with my dad, as well
