Wilson1911 Posted April 18, 2004 Posted April 18, 2004 My wife drove my 04' LS430 for a few miles with the parking brake all the way engaged before she noticed that the red brake light was on :chairshot: . When she got home and told me about it, I went into the garage and noticed this weird, almost metallic burning smell. The best way i can describe it is that it smells like an electric power drill or electric motor that's been burnt out. I'm going nuts right now trying to think what that smell might be exactly, and if her careless and stupid mistake caused any damage. Anybody have any knowledge in this sort of thing/mishap? I can say right now, she's NEVER driving it by herself again
Senna4ever Posted April 18, 2004 Posted April 18, 2004 It means your rear brakes overheated, and POSSIBLY caused the rotors to warp, and/or the brake fluid to boil....both not good. I say possibly, because I once drove across a long bridge (could not stop on bridge, I would have caused traffic chaos) with a seized caliper. The rotor was glowing red when I stopped, but apart from a new caliper, nothing else needed repair. Have the brakes checked for sure, just to be safe, though.
Wilson1911 Posted April 18, 2004 Author Posted April 18, 2004 Thanks for the info, I really appreciate it. I'm just curious, but how can I tell if the rear rotors are warped? I know the symptoms of the front rotors of a car being warped, but I've never had to shave or replace rotors for the rear wheels before.
Senna4ever Posted April 18, 2004 Posted April 18, 2004 Probably the same as the fronts. The car shudders when the brakes are applied.
VBdenny Posted April 18, 2004 Posted April 18, 2004 Unless she was on the Interstate, I doubt if drivng around town for awhile would do anything other than shorten the life of your rear brake pads. I know exactly the smell. Why was the parking brake set? I have always found it a bad practice to use the parking brake unless you park on the side of a hill or something. The rule with parking brakes is use the all the time and jam them down good so you CAN'T move, or never use them. I'd take the car to Lexus and tell them about the smell and have them figure it out. Since it's under warrenty, they won't charge you. If they ask you if you put the parking brake on, you can honestly say YOU didn't
JPI Posted April 18, 2004 Posted April 18, 2004 Have them check out at your local lexus dealer. If your rear brakes are warped you will fell the vibration in the rear when applying brakes. I doubt it though. Good luck. JPI
SW03ES Posted April 18, 2004 Posted April 18, 2004 Also keep in mind that the Lexus' parking brake is a interior drum, not the exterior disc that you use for normal braking. So theres no way theres any damage to the actual service brakes, but there may be to the parking brake. Drive it around, test the parking brake for grab, if all seems normal than its okay. The smell is going to linger a while.
VMF Posted April 19, 2004 Posted April 19, 2004 yeah ur parking brake is a drum and its not connected to your hidrauylic brake system. it uses the hand brake cable to engage and disengage the brake. so dont worry bout it. its nothing. just check if your hand brake functions properly - put it in neutral on a lil slope and thats pretty it.
SKperformance Posted April 19, 2004 Posted April 19, 2004 Highly impossible to warp a rear disc since it is the drum and it is going to get heated evenly. You would have worn down the shoes inside and the e brake might need adjustment after. But you never jam the brake as hard as possible ,just enough force to make the car stop rolling.
Senna4ever Posted April 19, 2004 Posted April 19, 2004 Also keep in mind that the Lexus' parking brake is a interior drum Really? I didn't know that. Guess I need to research my car a bit more!
VBdenny Posted April 19, 2004 Posted April 19, 2004 Beside, your parking brake only needs to work once a year anyway. When you get your car inspected. That is the only times mine has ever been used.
