soarer479 Posted July 3, 2004 Share Posted July 3, 2004 yes when your pads get too thin they your e-brake light in your dash will come on when your e-brake is not up thats when you know its time to change those pads Quote Link to comment Share on other sites More sharing options...
mbpgawest Posted July 3, 2004 Share Posted July 3, 2004 In my '97 LS owners manual it shows that if a light comes on that looks like and "O" with some dashes around it, than your brake pads are worn . They call it a "Brake Pad Wear Limit Warning Light." I know on my car there are 2 sensors both on the right side brakes (one front one rear). You don't want to let your brakes get that worn down, the sensors are about $70-80 each and must be replaced if the light comes on. Quote Link to comment Share on other sites More sharing options...
93LSOwner Posted July 3, 2004 Share Posted July 3, 2004 So, you should replace the brakes before the light comes on, so the sensors wouldn't mess up? One of my friends has a GS and the car was making funny noises when applying the brakes and the mechanic said that the car needed new brakes but the warning light didn't come on, he replaced the brakes and now the car is back to normal. How does the sensors work? He said there weren't any wires or any other thing with and around the brakes! Quote Link to comment Share on other sites More sharing options...
mbpgawest Posted July 3, 2004 Share Posted July 3, 2004 So, you should replace the brakes before the light comes on, so the sensors wouldn't mess up? Yes, replace brakes BEFORE the light comes on. The light comes on when ther is very little time before you are metal to metal. Change the pads before the sensor makes contact with the rotor, it saves you $$.

The light comes on when ther is very little time before you are metal to metal. Change the pads before the sensor makes contact with the rotor, it saves you $$. B) What is this e-brake stuff ??? The e-brake is a hand operated brake that is NOT DESIGNED to provide normal stopping for the car. It is only to provide wheel locking/braking in an emergency situation. The rear shoes are really thin and should last forever, hopefully. The pads, all 4 on my SC have mechanical squeal sensors, which contact the rotor when the pads get to thin. they WILL NOT damage the STOCK rotor just be REALLY annoying. Other models of Lexus like the BMW may have electronic sensors that can be damaged, and would have a dash light. Quote Link to comment Share on other sites More sharing options...
LEXIE Posted July 4, 2004 Author Share Posted July 4, 2004 thx for all of your replys. i guess i was too lazy to look in the owners manual but after redrockets post i checked and it mentions the mech squeal sensors. since my car is '93 vintage, it apparently does not have the electronic sensors. will keep close tab on pads at my routine tire rotations.

mbpgawest Posted July 4, 2004 Share Posted July 4, 2004 RedRocket, I'm 90% sure that your car will have the low brake pad worning sensor. Check your right side brakes and see if there are wires that come down to the brake pads. ;) Quote Link to comment Share on other sites More sharing options...
soarer479 Posted July 6, 2004 Share Posted July 6, 2004 well im not sure about your guys years but in my 97 when the e-brake light comes on its my censor for my pads ..... Quote Link to comment Share on other sites More sharing options...
lovlex Posted July 14, 2004 Share Posted July 14, 2004 the emergency brake shoes suppose to be thin? mine are thin in my sc400 and the mechanic that did my brakes said they were suppose to be thick and not almost paper thin as mine are?
