Can I do this on a 2006 GS300 with a power bleeder? I've read that if you open up one bleeder valve, the "computer" senses this as a problem and won't allow fluid to flow to that caliper. What if I pressurize the system with the power bleeder and then open all 4 caliper bleeder valves at the same time... let them all flow until all the new fluid is in the system and then tighten them all down? Would that work? Must the car be on?

 

no problem at all... just flush the brakes... leave the key off and the computer won't do anything... every car has a specific procedure, I can check tomorrow if you haven't gotten anything yet...

 

Ok, per lexus: 1) with ignition off, pump pedal 40 times. 2) turn ignition on, chech that the pump stops running affter 30-40 seconds. 3) pump the brake pedal 20 more time w/ ignition still on. 4) bleed right front, then left front calipers. 5)depress the brake pedal and bleed the right rear, then left rear calipers. 6) connect a scan tool and access the brake bleeding menu, follow instructions given - bleed the right front, then the left front with the brake pedal depressed. 7) if the hydraulic booster has been serviced, special tools are needed to bleed the unit.

Now, for the real world - I have not had issues with just bleeding everything as stated, and omitting the scan tool part.

 

for brake fluid flush/change, can we just ask pepboys to do it? do you think they will be able to do it? or is brake flush for Lexus needs to be done in a certain particular way that Lexus mechanic only know...?

 

Anyone can do it, for the most part... They should know the procedure though, and not all independent shops can...

 

hey guys- do you still need to pump the brakes if you are using an hand held vacuum pump- something like a mityvac? thanks

 

no........

 

I have a 99 GS400 and need to bleed all the lines. I have read there is a specific order to do this, and not necessarily starting with the "furthest" wheel from the master cylinder. Which caliper is really furthest on a 99?
