Who Should I Believe
hey guys,
got another problem.
took my car to lexus cos of a shakiy feeling at THE FRONTduring 60-70miles/hr when brakes are applied.
lexus diagnosed that the two front rotors were warpedand the back ones had hotspots.
so i ordered new front rotors and pad(still expecting them.)
But over the weekend, i went to my local mechanic(MIDAS) for a oil change and asked if they could replace the rotors when they came in. Upon taking off my wheels, the MIDAS people tell me my front rotors are PERFECTLY fine and that the problems were from my calipers at the rear wheels. they said i need to change my rear calipers to stop the shaky feeling i get in FRONT.
who do i believe.
i already ordered rotors and pads cos i trusted the lexus people. now these people are telling me this.
So i am thinking maybe it is time to sell the car and get another.
WHAT DO U GUYS THINK?
WHO SHOULD I BELIEVE?
in any case, where can i get calipers for the 94 gs300.checked ebaybut it seems the gs is the only one missing.

Not to sound like an ***, but who made the car? Is it the steering wheel that shakes when you apply the brakes or the car? If its the steering wheel, then yes, its the front rotors. If not, then maybe midas is right. Either way, you have the rotors on the way and since you bought them off Ebay, they were probably only like less than $200 right? If so just give them a try, if it fixes the problem, you probably saved yourself a good $500, if not, then atleast you know your brakes are gonna last a little bit longer.

same thot
that exactly what i thot.
and thats exactly what am gonna do.
since i got the car, i never had any engine problem or any problems besides the shaky feeling in thge steering.
we'll see what happens once i change the rotor which by the way is going to be my first DIY job

quick question though.
i have been reading up on do a DIY rotor change and etc but what i do not understandis how to tighten the bolts back to certain torques.
like some bolts need to be tightened to 22ft lbs .
my question is how do you know how many torques u have turned(is one entire rotation one torque?
sorry if this is a stupid question but it is smarter to ask questions of what one does not understand than remain foolish by not asking.
thanks

For the brake caliper slide bolts, a 3/8 inch drive "click" style torque wrench is best. A 14mm socket is used. For your wheel lugs, a 1/2 inch drive (also "click" style) torque wrench meets requirements. A 21mm deep 6 point socket fits most standard lugs The use of a torque wrench assures the bolts are tight enough not to fall out, yet no so tight as to damage by stretching or snapping the bolt in the caliper. And as important, the bolts are tightened evenly and pressure is distributed evenly. Note the Lexus lugs use a steel flat washer that presses into the wheel, rather than the nut grinding into the aluminum wheel itself.
You can overtighten with a torque wrench by continuing to tighten after the wrench clicks. It won't stop or break free on it's own..
China knockoff torque wrenches are usually less than $20 each... Sears Craftsman, about $100 each... Laboratory - Model grade, start at about $400 each.
If the lug nuts are over torqued, this is a known cause of the rotors warping.... Lexus lugs are spec tightened to 76 Ft Lb. (Dry - no lubricant) or 71 Ft Lbs. (Wet - lubricated with grease). Most tire shops over tighten the lugs...they like to document and tighten Lexus lugs to 85-90 Ft Lbs. This is good for many air impact wrenches they use. But, this is too much and yet relieves them of liability due to loose lugs. It is also suggested to loosen the lug "lock" first and tighten lug "lock" last.
Lastly, always return the torque wrench to it's lowest setting when storing. This insures you don't put the wrench out of calibration by constantly compressing the internal release spring.
Safety first, use jack stands when working on the brakes.. never rely on just the jack.
and Check you work !
