So I was driving my wife's '01 EX sedan today and noticed a horrible grinding/scraping noise coming from the driver side front rotor.

The grinding/scraping noise wasn't consistent but would happen even when not braking but just after braking. It was really pretty loud. I drive her car fairly often (since my '97 is more suited to the track now) and hadn't noticed this yesterday. Her brakes had been squeeking a little but I figured it was just the pads.

After getting home I see the carnage. This is the driver side rotor. Passager side looks normal. What caused this? It looks almost like the pad broke and is digging into the rotor. Is this rotor now toast or can it be fixed? Let me know what you think. Thanks!

 

did u wear the pads down to the backing plates?

 

That carnage appers to be caused by worn out brake pads. I recommend brake inspections more often. You might be able to machine the rotors if the deepest groove does not bring the width of the rotor below spec.

no I checked for that and the pad still has a little left. And the passager side is fine. Why would they wear unevenly?

The brakes have been squeeking for less than 2 weeks and I just had the car inspected in May with no problems. Its only had 2400 miles on it since the inspection

sticky/stuck caliper?

 

it can be fixed with a "accord for dummies" method but it's a last resort ordeal...throw a set of new pads on your front rotors and just drive like normal. eventually the damaged rotor will resurface itself. however your are then stuck with little rotor / big rotor.

your situation happened to me when i first got my car, and my result was the above method because i was doing football and not working. it was fine until i changed the rotors again though.

 

I got my front rotors machined at a local machine shop for $25 bucks and an hour wait. Probably good idea since the accord rotors are notorious for warping.

 

i had this same problem, and i seem to think that the proportioning valve is out of whack... my right front and left rear wore down considerably faster that the other two wheels...

This will not happen. the rotor will never be cut more then the pads. The brake pads are softer then the rotor, thats why they wear out faster. Small grooves and be smoothed out, but not resurfaced. you will ruin your new pads if you just throw them in with that rotor.

Measure the rotors, see if they are machineable (not a good idea anyway with the low cost of rotors) and if they are too scored up, replace them.

It is never a good idea to cheap out on brake components on your car.

 

i paid $20 for the bendix pads from advanced...my rotor shall i not use the word resurfaced but rather regroved it's ridges. but yes, it <u>can</u> w3rk.

This is true. Even here in Beverly Hills where I work people will cheap out on resurfacing the rotors and opt for a pad slap...The pads eventually smooth out the rotor but at the cost of the life of the pad

only a half-life

 

or the piston inside the caliper it pushing the pad unevenly on the rotor.

 

What if one of your caliper slider pins is stuck, that was the case on the rear pass rotor on my 1993 Accord SE and the rotor looked just like that. I ended up replacing both rear calipers anyway, but that might be the cause.

Ony reason your rotors are warping is because of excess heat on the rotors form either constant pressure of a caliper, or factory defect, to completley avoid this, they invented Crossdrilled sloted brakes, highly recommended for any car, and their only a couple$ more...
