popeye2 Posted August 26, 2007 Share Posted August 26, 2007 After parking my 2001 OBW at an outdoor airport parking lot for 2 weeks, I'm having problems with my front brake pads/ rotors. Apparently the pads stuck to the rotors and when I backed out of my spot the pads broke?? or something as now when the brakes are applied you hear a thump, thump, thump as though something is stuck to the rotor? Any likewise experiences ? Quote Link to comment Share on other sites More sharing options...
nipper Posted August 26, 2007 Share Posted August 26, 2007 Usually it just takes some drtiving around to break off all the rust. This is not an uncommon thing with disc brakes. This is also why you dont set the parking brake if your going to be away fopr a long peroid of time. It should go away. What airport? Was there an excessive amount of rain? nipper Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted August 26, 2007 Share Posted August 26, 2007 It's not uncommon for the brakes to be a little sticky after a vehicle sits for a few weeks. Make a few good stops from say 60 to break them back in. Carefully of course. I have been unpleasantly surprised a few times at the brakes not working so well the first few times after the vehicle sat. Then if you are still hearing some weird noise it may need to be looked at. If water got past the rubber accordians between the caliper piston and body, the caliper may have corroded somewhat and may be sticking.

Into the dealers tomorrow, the service rep said it's unusual not to correct itself after a few days of driving. the brakes/rotors had about 20k miles on them. The rotors at this point "feel" fine.

Manarius Posted August 27, 2007 Share Posted August 27, 2007 Brakes are a lot more durable than people make them out to be. I think that it will correct itself eventually. Quote Link to comment Share on other sites More sharing options...
popeye2 Posted August 30, 2007 Author Share Posted August 30, 2007 As it turns out the dealer/mechanic cleaned some deosits of rust off the rotor and all is fine. I've never had that problem last so long, had me worried! Thanks for the assurrances. Brakes are a lot more durable than people make them out to be. I think that it will correct itself eventually.

Kilroy Posted August 31, 2007 Share Posted August 31, 2007 I have this same problem with my Acura RL. It sat in the garage for 5 months without moving (over the winter) and when I backed it out in the spring the brakes were rusted to the rotors. It broke away and as I back down the driveway I could feel and hear as the brake pad went past the high spot that the rust left behind. Even after removing the wheels and taking some sandpaper to the high rust spot on the rotors I have a little of the rubbing remaining. Oh yea, anyone want to buy an Acura? http://edmonton.kijiji.ca/c-cars-vehicles-cars-over-5K-1998-ACURA-RL-US-CAR-IN-MINT-CONDITION-W0QQAdIdZ21712037 Quote Link to comment Share on other sites More sharing options...
Petersubaru Posted September 1, 2007 Share Posted September 1, 2007 would useing ceramic pads cause this same problem Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted September 1, 2007 Share Posted September 1, 2007 Yes they would. No pad can be immune to the rusting of the rotor. Quote Link to comment Share on other sites More sharing options...

porcupine73 Posted September 7, 2007 Share Posted September 7, 2007 Here's what the old rotors from my '00obw looked like after sitting outside for about 2 weeks: The pipes they are sitting on have been there for 30 years. Quote Link to comment Share on other sites More sharing options...
Setright Posted September 7, 2007 Share Posted September 7, 2007 Those pipes probably have a high-ish content of silicium, which causes a very fine structure in the rust, meaning less of the big flakes. The brake discs don't have silicium in them, they would be too weak for the job. Manhole covers tend to have high silicium content too, the weaking is compensated for by the large thickness of the cover. Quote Link to comment Share on other sites More sharing options...
Manarius Posted September 8, 2007 Share Posted September 8, 2007 And if you grinded down the rotors, they could look next to new. Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted September 8, 2007 Share Posted September 8, 2007 Yes I'm sure they could be turned. I was just trying to show how much they can rust in a few weeks. Those would be noisy for a while. I think they're the least expensive rotors from autozone; it was what the used car dealer threw in for 'free'. They don't have the nice 8mm holes to drive them off the hub. Quote Link to comment Share on other sites More sharing options...

On my Legacy, I pulled the rotors off without even needing to drive them. As soon as I pulled the caliper, the rotor was just dangling.

porcupine73 Posted September 8, 2007 Share Posted September 8, 2007 Yes I think if the rotors haven't been on too long and/or if you don't live in a salty area, they will come right off. I don't know, these rotors I had to heat with the mapp and use about a 6lb sledge on them. The 8mm holes work great to force the rotor off - if the rotor has the holes. When I put the new rotors on I brushed and cleaned the hub and everything and put a protectant on the interface parts. Those rotors are always free whenever I remove the wheels.
