dads-car 01-23-2006, 09:08 PM Could it be considered normal when brakes are 'grabbing' even with no braking pressure being applied by driver? Front and back. Noise only occured while moving. All four wheels have disc brakes.
Backing out of garage this morning and there is a really hideous metallic scraping noise. I figure it's got to be the brakes (only logical thing), but I'm not using them. Couldn't be the wear indicator either, the guy who replaced a CV joint for us said that the brake shoes at the front were as good as new.
It's a mixture of squealing, scraping, and grinding. Giving the brakes a good check on the street did not have a great effect. Noise did not increase as braking pressure was applied, and a noise continued after braking pressure was released.
Is it anything to worry about? Seemed to go away after a while of drivng. But, I've always noticed the rear brakes have sometimes been reluctant to release when pushing the car, backing out of garage, etc.
stiller fan 01-23-2006, 09:11 PM do you have drums or discs in the back? if drums, check adjustment.....
as for discs, here in the US, i have been told that they automatically adjust.... not sure if that is true or not.....
BenjiBoy650 01-23-2006, 09:26 PM Maybe a rock stuck in there. But since u said it goes away with driving, I'm inclined to think it is the pads.
Inspector1 01-23-2006, 09:27 PM Brakes not releasing is not a good thing. Most common reason is fluid contamination making all rubber components swell up to twice normal size.
Check the master cylinder for signs of contamination(Milky or clouded fluid)
Only way to repair is to replace all rubber components in system :thumbsdow
Do the brakes get real hot after driving?
Hope thats not your problem..

dads-car 01-23-2006, 09:53 PM If the discs in the rear are self-adjusting then I guess they're probably fine. Usually, those will free up by the time I'm out of the garage.
I checked the fluid in the cylinder earlier today, it looks fine. Has not been replaced in 50,000mi, so any chance of human error is small. Brakes still seem to behave normally.
Since there have been roadworks down the road I'd suspected a rock or stone, but didn't see any scrape marks/gouges on the rotor or anything, so wasin't sure.
Brakes do not get hot nor fade with use.
What do the brake wear indicators sound like, out of curiosity?
Inspector1 01-23-2006, 09:59 PM Metal to metal grinding, Just pull the wheels and take a peek.

princess 01-24-2006, 07:18 AM You don't have to be applying the brakes for the indicator to make a sound. It happens when rolling slow too.
Sticky calipers....? :dunno:
SSMV6 01-24-2006, 08:19 AM If the noise pitch, tone, or volume does not change when applying the brakes, then it's most likely not the brake pads. I would still check the rear brake pads just to make sure. 50k miles can burn up the 2-3 sets of rear pads in some cars... Make sure you check the inside and outside pad for even wear.
Does it sound different while moving forward vs reversing? Is the noise coming from only on one corner of the car? Have someone sit in the back and stick their head out to listen for the noise.
Check your parking brakes. It could be a stuck cable.... How's your gas mileage?

13 years, 100,000mi, and the brake pads are the ones it came with.
Since Princess said that the brakes don't have to be applied for the wear indicators to sound, then perhapsn it's them. Can't tell whcih wheel, but it's the same going forwards and backwards.

The brake pads don't last nearly as long as they used to... The consumer wanted a quieter brake pad, so the MFG responded by installing a softer compound pad but those didn't last as long, but is much quieter. When that brake pad started to wear out after 20k miles, the consumer complained that the pads didn't last long enough so the MFG installed harder compound pads to compensate. In the meantime, the consumer asks for more and more standard options, driving up the weight of the car and increasing the load on the brake pads, lowering its life. The consumer complains of short brake life again.... Do you see where this is heading to? The MFG is always fighting a losing battle...
Anyway, with that aside, we are talking about your dad's '93 Accord, right? :lmao:

Yeah.. He dries his '05. The '93 is in his name because of speeding tickets :D.
No noise today.. Guess it must have been a stone as Ben suggested.
SSMV6 01-25-2006, 06:21 AM Were you sharing your forum name with your son? From your earlier posts, it seems like you're talking about the cars as if they were your dad's... :dunno:

No... I'm the son and drive cars that he owns. He doesn't come here.
He's not a car person... But I am, and as he is an accountant, I need to justify every expense - and since the car is starting to show its age I've been figuring out the correct maintenance so that it doesn't die an inexpected death on us.
:)
dads-car 01-25-2006, 11:34 AM Oh, and he drove the 1993 like a baby. I guess it was just the manual transmission, because he drives his new car (AT) a little lead-footed - as shown by the speeding ticket which he received in the mail today.
:D
SSMV6 01-25-2006, 11:49 AM OIC.. :)
