Lexus SC430 :: How To Change Brake Fluid
Is there a write up on how to change the brake fluid or is it the typical pump, hold, then open and close the valve on the caliper from farthest to closest? Also, is it ok to use dot4 super blue fluid and do we have a vendor that sells SS Brake lines?

What is the process for flushing the brake fluid for a 2007 or any other year from the Lexus Service Manual for our cars? I have read what I believe is the correct process on various threads but would prefer to read the service manual directly.

The leak appears to originate somewhere around the master cylinder but I cannot locate the exact spot.
I noticed the problem when I started the car and it began to generate white smoke in the drivers side. I also knew it was not oil or ATF because brake fluid smells different. I pulled the cover by the master cylinder (MC) and could see an area that was wet under the MC.
I may have a reservoir leak but I cannot pinpoint at this time. Photos will be provided later if I can take some that show the issue.. I do know they are expensive and I do know that Toyota and Lexus recalled several models for a leaky reservoir.
Lexus SC430 :: Squeal From Brake Fluid Reservoir Area
Just fired up my 2002 SC430 (115k miles) for the first time this year, so it's stood for over six months. Connected fresh battery, checked all fluid levels etc. Runs fine and purrs like a kitty BUT I'm getting a loud intermittent squeal (like you might get with a sticky pump or a slipping belt). Almost like a loud "meow" in duration & tone. So loud it can be heard from 20' away. Sometimes once per minute or two, sometime several times in a row then silence for a few minutes.
This is from the area where the Brake Fluid Reservoir is (on Right Hand Drive SC430 this is right by the Windscreen on the left hand side of the engine bay as you look at it from the front of the car (may be reversed on Left Hand drive models). Directly in front of the Steering Wheel.
(ABS) check light is on. Also "VSC" & "VSC off" check lights on (probably related to ABS being in check and VSC button does nothing to clear those lights). Also getting the buzzer alarm from the dash. Pumping the brake pedal and driving the car forward/back 10' several times on the driveway doesn't clear this.
Now, this may be that the Brake Pads have bound to the Discs (Rotors to you left-pondians). I may need to pop the wheels off and free up the Pads in that case.
Lexus SC430 :: Transmission Fluid Leakage
I have noticed a few drops of red liquid on the driveway lately, presumably transmission fluid leaking. Where the leak typically starts, if there is a "typical" leak. Is it generally an expensive fix?

Raised car on jack stands. Totally level. Opened up the check cap, the one with the allen key.
5.5 cups of black fluid came out (car only has 25K miles on it).
After it finished draining from the check plug, I opened the drain plug. 4.5 cups came out.
Total of 10 cups. So it appears the trans had a little more than .5 qts too much. The shocker though is that the check plug let more than half of that drain out, so it appears tube inside the pan is defective and I'm going to have to make sure to put just the specified amount of fluid back in and hope for the best.
I'm wondering if I should just put back exactly the amount that came out which would be 2.5 qts rather than the specified 1.9 qts.
Lexus SC430 :: 2002 - Pink Fluid Seeping Around Top Of Radiator
Have noticed some pink fluid seeping around top of radiator, which has created a bit of a mess in the engine bay. Is this indicative of a radiator leak? I don't see any visible cracks, however not much of the radiator is viewable. If replacement is necessary, what OEM alternates are recommended? car is running fine and not overheating. It's an '02 sc430 with 171K miles.

The low wiper fluid warning light on my 2004 SC 430 will not go out. The fluid ran out after I was adjusting the spray to properly hit the windshield. After I refilled the fluid reservoir the warning light would not go out. Any way, besides "remove the bulb?"

Just got my second sc, after I crashed my first one and the little button that releases the wiper fluid to clean the windshield is gone, how I can find such a small part? Does the sc300/400 use the same wiper lever/arm as ours?

One of many issues I need to fix - headlight washer fluid cover seems to be stuck open. i applied moderate force to push it back in, but it did not move, and i do not want to risk breaking it.
I'm thinking some wiring isn't right, maybe connectors never got reconnected.. the auto adjusting headlights don't work either, and the washer fluid line from the firewall that runs to the washer fluid tank was hastily crimped on due to the plastic hose fitting being most likely broken off or lost. Does the bumper need to come off to mess with it? guessing yes.
Lexus SC430 :: Rubber O-ring On Power Steering Pump Solenoid Valve Leaking Fluid
My car is in the shop and has a leak at the Power Steering Pump. The rubber O-ring on the Power Steering Pump Solenoid Valve (p/n 4417030120) is leaking fluid. The Solenoid Valve is ok, just the Rubber O-ring is bad, but it looks like you have to buy a complete new Solenoid Valve to get the O-ring (a lotta bucks).
I did find a Lexus Power Steering Pump rebuild kit online at, but I can't see if it includes the solenoid valve o-ring or not. Have to replace their solenoid valve o-ring?
Prius (2004-09) :: Brake / ABS Lights On When Car Started After Being Parked For 3 Weeks
I parked my car (outside) and went on a business trip for three weeks. When I came back last week, when I turned the car on, the brake light and the ABS light were on. And it hasn't turned off since.
The car was working fine and didn't show any sign of troubles prior to me parking it, no funky light was on. What could be the cause? It wasn't driven during three weeks. What could have deteriorated to cause these lights to come on? The car seems to be braking fine.
FYI, before getting to my car last week, after leaving parked for three weeks, I mistakenly pressed the Panic button. And I didn't realize that the Panic button got stuck and was continuously in circuit. And it stayed like this for an hour before I realized what happened and fixed it. Not that I think that it can have an influence on my current problem, but thought I would mention it anyway...

View 4 RepliesLexus SC430 :: Brake / ABS And VSC Lights Powered On
2002 SC430, 150,950 miles.
Had new front brake pads, re-surfaced rotors, new windshield fluid level sensor installed, 4 x wheels balanced and rotated on 8/11 at Lexus Dealer. Picked it up 8/13, drove 30 miles and it sat 8/14-8/16. Drove to work on 8/17, and on the 18 mile freeway trip home yesterday, the Brake and ABS dash lights came on as I was making a gradual left turn with damp roads.
Thought nothing of it initially, thought my knee had hit the e-brake as mine is very touchy and as long as you pull the release, the light goes away. Not this time. The Brake and ABS lights were on for 4 minutes, then eventually the VSC and VSC OFF dash lights also came on. Steering became difficult, checked brake fluid (ok), checked power steering fluid (ok). No leaks underneath, all fluid levels were just checked on 8/11 and were fine/topped off.
Parked it, set up an appointment and just dropped it off this AM. I've read brake booster, speed sensor, alternator, skid control unit .
I am hoping it's just the alternator, which makes sense with the difficult steering and the lights going on one by one. If the alternator isn't outputting enough volts, those lights will trip. I've had all O2 sensors recently replaced, other standard preventative maintenance done (timing belt, thermo, etc). I'm just hoping it's something manageable and not something that makes me wonder if the repair is worth it (vs the value of the car)...
There are no CEL lights, just the above (no codes to my knowledge).

View 3 RepliesLexus SC430 :: Brake Pedal Drops When Car Comes To Complete Stop
After replacing several front end suspension parts I noticed an issue with the brakes. The car stops fine and in a straight line but right before the car comes to a complete stop the brake pedal drops about 1/2inch and if I am not holding the wheel, I see it move to the right ever so slightly. It does it every time and I am thinking that a component was either damaged or is not installed correctly.

So, I have Stoptech rotors and brakes, and it squeals when (a) it's warm after a few minutes of driving and (2) only when I initiate braking softly to slow down, but disappears after braking firmly to stop. Brake pads have about 80% left on them.

I have a slight squeal from the left rear brake when in reverse. Doesn't do it all time and never when roads are wet. I disassembled the caliper and all looks good. I replaced the pads about a year ago and the noise just recently started, so its hard to blame that. I did not use the brake anti-noise lube......but I never have.
