Hello
How many of you guys that are around 30k miles changed brake fluid? By the lexus manual its recommended to change it every 30k miles. When i bought the car, i checked with lexus and its has not been done. I am thinking of changing it, how important is it? I asked my mechanic and he looked at it and said it was fine. Also i hear that you can't just drain and refill because of all the lights that will light up on the dash. You need a special machine that lexus and toyota have. Any input and personal experience would be greatly appreciated.

 

It's a regular maintenance item for any car. Brake fluid absorbs moisture and eventually needs to be changed to prevent rusting of the brake components. Do you really need to ask yourself how important brakes are?

It's not an expensive service, just do it (at toyota?) for peace of mind.

 

i did my 30k service at toyota and they didnt change brake fluids,,

 

It's always a good idea to do it. Even if it doesn't looks dirty, it's hygroscopic (absorbs water) as Jay pointed out. Definitely not something you want overlook and not something you want to do yourself either unless you have Techstream to assist you.

 

as others said, you don't want moisture in the setup.

you can do the bleed yourself if you want, just make how otherwise computer might throw you an error code (though you have gs350 and that might be a good thing since you don't have ecb)

 

Guys, tomorrow I will be replacing my rotors and brake pads. Do I need to worry about fluid change? I only have 7000 miles on my car?

 

^nah, i woudln't worry about it.

 

Thanks appreciate it!

 

I've got 50,000 and I wanted to do it myself... I already recieved my maintanence kit from Sewell Lexus. Anyone want to make a "DIY" for bleeding the brake fluid properly on GS350 please ? ? ? ? ?

 

Thanks for all the input.

 

I've just gone over 30k and haven't changed the fluid.

I use my brakes very little as I do mainly highway driving and was advised that it might not be worth doing if that's how I use the car.

Any thoughts on whether usage impacts when you should change brake fluid?

 

personally, 30k or 2 yrs i bleed the brakes. i would hate to suddenly find there are bubbles and such in the system or reduced performance due to moisture

 

Don't you require a special machine/tool to do the brake fluid on our cars?

 

use a MityVac for easier bleeding.

 

Hold on can i just bleed it from the caliper brake lines and fill new brake fluid and pump it? I thought i seen someone saying that lights light up on the dash like VSC........ if you do it without special machine that lexus and toyota have!
