    Correct it's not an obd car but it does have engine ecus, abs ecu, etc. Surely there must be a diagnostic tool that communicates with these systems?

    I'm asking about a 355 in any case

    There is no tool. There is a complete manual that tells you how to troubleshoot the system. The flashing light tells you the trouble codes.

    Ahh well there may be the confusion. The 355 was Teves for a short period perhaps < 1 year or so, not entirely sure, and is the same as the 348, Mitchell is right no fancy tools. AFTER the Teves years with Bosch in the 355 it's different there is diagnostic with scan tool yes which may be what your thinking in which case it is not Teves and this post is irrelevant.

    Teves = old school
    Bosch = new school

    Teves was on for all 1995 355s and most of 96 355s as well.

    I first depressurise the system (get the old fluid out of the accumulator), then suck all old fluid from the reservoir. When you then pour fresh fluid into the reservoir and start bleeding with the key in "acc", the pump will suck fresh fluid and expel the old fluid which was in it into the accumulator. Then switch the key to "off" and continue with pumping the pedal to expel the small amount of old fluid (that came in from the pump) into the line being bled. You can repeat bleeding with ignition in "acc" and "off" a few times to make sure all old fluid has been pushed into the brake line and out from the bleed nipple. It is better to extend the overall bleeding process somewhat after the clean fluid shows coming out of the bleed nipple to ensure good flush everywhere. I don't mind using double the quantity of fresh fluid than what is required to fully flush the system (2 Lit instead of 1 Lit, fluid is cheap).

    I guess that would save some brake fluid. :) But after that I don't see the point of turning the ignition on an off. With the ignition at ACC, once brake pedal is depressed, opening the rear bleed screws will expel fluid from the accumulator and rear lines and calipers. As the pressure drops the pump will cycle on, recharging the accumulator and expelling more fluid from the rear.

    What do you gain by switching on and off and pumping the brake?

    After you have depressurised the system the first time, all old fluid will be out of the accumulator. When you then switch the ignition to "acc", the pump will push the residual old fluid from itself, and from the suction line reservoir-pump and push it into the accumulator which will later mix with the fresh fluid coming from the pump. In order to expel this mix from the accumulator, you need to continue the bleeding (pumping the pedal) with the ignition "off" so that the accumulator can expel the mix into the MC and the line you are bleeding. The next ign' "acc" will probably push only fresh fluid into the accumulator but I would repeat the cycle at least one more time. If you just do the bleeding with the ignition continuously at "acc" the accumulator will not be completely emptied (as the pump will come on before that, probably when the accumulator is half-empty) so some old-new mix will remain inside the accumulator.

    I see your point. Seems the difference is just how many cycles you would have to go through to refresh the accumulator. If you assume the accumulator empties 1/2 on each cycle then the amount of old fluid would be 1/2^n where n is the number of charging cycled. So 5 cycles you would have about 3% old fluid. I just open the rear bleed, depress the pedal and let it do it's thing. Probably takes a little more fluid to flush than the way you are describing. :)

    Brackets are complete. I'm very pleased with how they came out and hope everyone else is as well.
    Anyone who just wanted brackets, they will be shipping out. I am still waiting for the pressure lines to come in so the complete kits aren't quite ready. As soon as I have the lines they will be going out as well. Everyone will be getting emails with tracking info once they ship.

    Well technically the 348 IS an OBD car, it’s just OBD 1 not the advanced OBD 2 that became mandatory in the US in 96.

    It has On Board Diagnostics (OBD) but you get codes from counting flashes after triggering the self diagnostic. No way to plug into it but they (engine ECUs) have removable chips you can pull out and reprogram etc.

    I just received my kit and the quality of the bracket and hoses is really good. It all looks factory OEM and will blend in seamlessly with the brake pump and car. Thanks again for putting together this kit!

    Got mine, I'll go one more, it was packaged and finished like a commercial product, there was more effort in this kit than was really needed, so I for one appreciate it Trevor! Top shelf.

    I may want to snag one of those kits for the future insurance. I'm almost positive I have the Teves system in my 355. Which is a 97 model so that seems oddly late or past the switchover to bosch timeline.
