Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / June 2005Useless break wear indicators?
Can those wear indicators on disk brake pads be heard by people who are driving around with their windows rolled up? I've noticed lots of cars squealing constantly because of them, and a friend of mine who's fussy about car care (but doesn't know about cars) said that he never knew tha this brakes were squealing until somebody told him. He had his brakes fixed the next day. Why don't they make wear indicators by notching out the rotor near the hub so when a metal area of the pad scrapes it, it won't only make a pulsating squeal but will also cause the brake pedal to pulsate? I can't imagine this costing more than the metal fingernails they put on pads now because the notches can be molded into the rotors and no extra machining would be required. > Can those wear indicators on disk brake pads be heard by people who are > driving around with their windows rolled up?

How can one drive around all week and not notice the squealing? >> Can those wear indicators on disk brake pads be heard by people who are >> driving around with their windows rolled up?

Those that took care of their cars would either inspect the pads or use a mechanic to do so. 2. Those that didn't take care of their cars used the earlier built-in pad wear indicator. The metal-on-metal scraping was audible to all but the deaf and could be felt in the pedal. Not a whole lot has changed since those days except that the people in (2.) drive around wondering what that squealing noise is until it converts to metal-on-metal scraping. > 2.

Even better is when the scraping noise changes ever-so-subtly to a different, worse, more alarming scraping and loss of braking ability -- when the pads become so thin they fall out of their holders and the piston becomes the new friction material. Give these guys credit, though. They usually come right in when that happens.

My wife with her super sensitive hearing would agree with you. But, since she is aware of my hearing loss, she knows I will never hear it. I do regular inspections of such things but, I have her traind as my ears for things that go wrong along the way. I am, however, intolerant of those who do not use whatever senses they have to pay attention to changes in their vehicle that may be related to needed maintenance. It never ceases to amaze me at some of the things I see wrong with cars to which the drivers are totally oblivious.

I've noticed many cars running around with squealing brakes, and I know that it's hard to hear outside noises with the windows rolled up, especially if the car is naturally noisy like my Escort. I sometimes cruise around with all the windows down to check for funny noises, and I once found a bad tire that way. |
