It just hadnt gotten to the point where there was low pressure in the system, if the brake fluid was above the min line makes sense no lights would illuminate. The system doesnt know theres a leak, it measures hydraulic pressure and it measures the amount of fluid in the system.

A lot more fluid would have had to have leaked out before you would have had an issue with the braking system

 

they screwed up that badly and all they did to remedy it was tighten the bleeder, top off the fluid reservoir and spray down the car?
you deserve better than that! Brake fluid wreaks havoc on rubber and your suspension parts and tire got soaked in it.

 

What more would you want them to do? Having brake fluid leak out isn't damaging the car, wont hurt anything. Fix the leak, clean off the fluid there isnt anything more to do.

 

Damn, I hate to hear these kinds of experiences. I too had bad experiences with the Lexus dealership. It's Toyota luxury division, and you would expect high quality service work and not Jiffy Lube type of service. For $185, I'm sure the tech siphoned the old fluid out of the reservoir, and bled the front brakes only. They probably didn't even touch the rear brakes because it required Techstream to open the solenoids. For the full brake flush service, it would be close to $350-400. I've done the brake fluid flush myself using the Techstream so I know what's involved.

Add this incident to your live and learn and move on. Cheers!

 

That is a great point. I am going to call them on Monday and ask them if they just did front or front and rear.

 

I actually would alike an apology for endangering my life. Nobody offered me any yet. They have tried to pin it on me though.

 

Thats just not going to happen. No business will ever apologize to you for that sort of thing because to apologize would be to admit fault and liability. Their attorneys won't let the "apologize" even if they want to.

Its business, just be happy you were okay and the car is fixed and decide whether or not you want to use that dealer in the future.

 

While it has been an arduous experience to be sure, modern brake systems are designed to have dual master
cylinders and redundant hydraulic lines. Trace away from the drawing of the brake pedal and notice two circuits
leading to valve bodies that split the pressure. You would have still had some measure of braking even with a
broken bleed fitting on one wheel. Glad they cleaned up their mess and stepped up with the home delivery.

 

I don’t think a LS has dual reservoirs, so it is possible for the entire fluid set to lose all fluid. If I am correct, if one brake loses pressure, only two brakes still work....then all fluid eventually is lost by the leaking line.

 

I find it hard to believe that a modern car like an LS has no fail safe method in place if a leak in the brake system were to occur. Some sort of back-flow or something so that all of the fluid in the entire system is not able to leak out of one faulty bleeder. Even my 1975 Silver Shadow has accumulator spheres that can act as an emergency system in place beyond just pulling the E brake.

 

I'm sure it does.

 

No it's not lol, the older type vacuum systems are way more reliable.

It does have a system to prevent all the fluid from leaking out one line and the reservoir has a mechanical devision to separate the two circuits so only one can go totally empty if the system doesn't catch the loss of pressure. It's similar to Mercedes check ball system that if pressure is lost it seals that line entirely. Also makes bleeding hell. You can see in the diagrams the two paths that the system is split into from the master

 

Well those also are a totally different system that has two twin loops that can have one totally loose all fluid and pressure and the other will still work perfectly. If you loose pressure in both loops though you are screwed, the accumulators only serve to keep pressure stored and if you break a line past the 2nd valve block they can't send force to the wheels or suspension. I have worked on several of those cars and it's a brilliant system but if you lose pressure on both circuits (Brake1 and Brake2) you are dead.
