I had a mechanic change brake fluid in my '06 IS 250. He drained it from one wheel - front passenger. This didn't look right, so I check out some threads and found that it has to be drained from all four wheels?

Did he just drained part of the fluid and not completly got rid of the all old fluid?
and by adding new fluid just mixed it with old?

Do I need to redo it properly and drain from all four wheels?

Hopefully, it's not causing any damage

Thanks!

To do a correct brake fluid drain/flush you slightly pressurize the system, start at the wheel farthest away from the master cylinder, and start to drain from that wheel. Once you start to see the new fluid, tighten up that drain and move on to the other rear wheel. Continue this process until you have done this to every wheel. This will ensure all of the old fluid is removed. They did a quick/half-*** job.

Oh, to answer your question...is it safe, yes. Is it optimal for longevity...no. And, did you give them OEM Toyota brake fluid to use? Toyota/Lexus have special treatments built-into the fluid for these vehicles.

Just to follow up, you should do the wheel with the longest brake line from the master, which is often not the one that is actually furthest from the master.

In the ISx50 LHD, this wheel would be the left rear wheel. So the "correct" order is left rear, right rear, right front, left front.

Does anybody here attempt to cycle their ABS module when bleeding brakes?
It needs specialized equipment, but it ensures you get all of the old fluid out.
I've not seen anyone mention it, so I was wondering if it were even necessary on the IS.

That's a good point Jeff...and I had no idea that the rear left had the longer line. Odd.

It's actually somewhat common, it really just depends how the brake lines are run under the car, several of my other cars were the same way.
