2002 SC430 - Brake Replacement due to age?
I have 2002 SC430 with just over 22,500 miles on it.
On a routine check, it was noticed the brake fluid has gone bad and should be changed.
My mechanic (independent) recommended that we replace the pads at the same time as the fluid simply due to the fact that they are the original pads from my 01 manufacture date.
I have a few questions for this forum:
(1) would you replace the brake pads? If so, would you do both front and rear?
(2) would you replace the rotors at the same time? Both front and rear?
(3) what brands of pads / rotors would you recommend? My driving is "spirited" but not "racing".
Many thanks.

Brake pads and rotors do not just go bad unless something happens to damage them. Pads wear down as you use them so when they reach below a certain thickness you must replace them. The rotors can warp do to heat or can also wear as you brake so when they reach below a certain thickness you must replace. If you don't feel vibrations or have another sign of wear I would not replace them. If it makes you feel safer to have new ones on then you should replace them. Good luck.

no that is ridiculous. brake parts dont have a shelf life.
sounds like you need to get a different mechanic because this one
is just trying to get money out of you but im glad you were wise enough
to not go through with it right then and there.
brake fluid is hygroscopic meaning it absorbs water so yes it does go bad.
when you press the brakes, the water in the fluid will compress rather than moving
the fluid, which means a less effective braking system.
when you apply the brakes, the majority of your vehicles weight is shifted forward, and your
front brakes do the majority of the braking, meaning your front pads will wear out much sooner
than your rears. you might replace your front pads 2-3 times before you ever have to replace your
rears.
also, the material of the pads you choose, when you eventually have to replace them, depends on you.
different materials could mean more OR less noise, dust, wear. its a compromise. so decide what
you want to compromise and choose accordingly.

Around 40K I replaced the (front) pads from Toyota, nothing done on the rotor.
I have 49k, I am told rear needs replacement, I'll wait for 55k

Wrong, water does not compress. It only compresses if the system heats to the point that the water turns to vapor. Then it will compress. No liquids are compressible.

lol yes indeed you are definitely nit picking now.
water vapor, which i referred to as air.
if i werent on my phone i would copy/paste the excerpts and references word for word, just for you iolmaster. perhaps later when im at a computer i will edit my previous replies to just to clear up any confusion

No need to replace pads based on age. Saying that if this were my car I'd order OEM Lexus new pads, front and rear from Sewell and pay the mechanic the labor to install while he's got it all apart. Probably good the turn the rotors at the same time. Then your done with the brakes for another 11 years.
Pads for all 4 axles will cost about $100.
