I actually have two questions. I just bought a car and put brand new brakes and rotors on (Less than a week ago). The rotors have already started accumulating rust spots, whats the easiest way to clean this and then prevent it from happening again, it looks like shit.

Also, I am selling my old car and need to get rid of the 'ABS' light that keeps coming on. Everywhere I look I hear that 9/10 times its because of a short in some sensor that goes to each of your calipers, but I still need to fix it. Autozone "cant read ABS signals" and both Midax and Car X "Don't have your connection". Regardless, the ABS light keeps coming on aprox. 1 minute after I turn the car on and start driving, never as soon as I turn the car on. Is this something that a wire short would cause? Because I feel a short would cause it to be on all the time.

Also, is there any way to pinpoint exactly which wheel is throwing the fault? I do not want to replace all 4 wires/sensors/fuses etc. if I don't have to.

Thanks in advance!

Considerably more expensive rotors is more or less the only solution to those rust spots, although it seems like if they're on the surface of the rotor they'll just rub off every time you drive it.

/e you can clean the spots off with spray brake cleaner applied conservatively (and WITHOUT a lit cigarette or spark of any kind anywhere near you... shit's volatile)

And on the ABS light issue I hate to ask the obvious question, but have you checked the brake fluid? If it's even slightly off on our Buick it throws up the code the first time you push the brakes after beginning to move.

Yes the spots in contact with the brake pads wear off, but not on the hub and everything else. I will try cleaning withe said brake cleaner, hopefully this will leave some kind of protective layer to prevent it happening again too.

Yes, the brake fluid is completely FULL! both reservoirs. And there is no squeaking, pulling, etc. And its not even that the light comes on when I push the brakes, its seems to me to be completely random.

Nope, brake cleaner doesn't leave anything behind. The reason it's so flammable is because it evaporates rapidly and completely.

If it's seemingly random, the ABS issue probably is a short or a loose contact. Finding out which one will probably require a professional mechanic. They've got more sensitive/specific tools for finding vehicle code issues.

so somethings evaporative properties determines its flammibility now?




youre just gonna have to deal with hub rust it happens.only way to prevent it is probably like some rust inhibiting spray paint. just make sure you dont get it on the machined surfaces of the rotor (it would probably just rub off but better safe than sorry)

Error in terminology. I said flammable when I should have said volatile. The evaporative properties of a flammable liquid substance often determine its volatility.

Just a thought but it would probably make the brakes fail/not work properly. You could apply a coating of something similar to Anti-seize. Their is alot of different compounds you could use to do this, but if it is only a cosmetic issue i wouldnt suggest doing anything at all except buying more expensive rotors that would be a rust resistant alloy. And just to reiterate it is probably a bad idea to do anything because it would cause the brakes to fail or not work properly which could result in a wreck.

As far as the abs light it should come on when you start the car. If it keeps coming on it could be anything from the sensors to the abs module. How old is the car? It could be a wire that is shorting out. The abs module it self could be bad. Take it to the dealer?

Its a 97 Acura CL. The light comes on when I start moving forward. I've figured that out.

Take it to someone that has a scanner that can read abs codes...

Thanks, but I'm starting to think that my connection is unique? Should be the same as a late 90's accord so I don't see why though.

If it were easy as this I would have done it already. Not driving 50 miles to the nearest Acura dealer.
