    Just to be clear this bracket I am making is an addition bracket, it is exactly what I had pictured in one of my previous posts. Essentially a bracket that bolts in place of the factory location that allows you to use your same factory pump bracket to bolt to it. You will use your same hardware to mount to the chassis and I will provide the hardware to mount your factory bracket to the new mount. Just want to make that clear so there is no confusion.
    I can look into what cad plating will cost, that would be a very nice finish to match everything.

    Rubberized black looks more factory chassis. I vote for that, but all of it will be under the front liner so it will rarely be seen. So it does not matter which finish.

    Is it OK to have the accumulator mounted horizontally, as it appears in the picture above?

    Not arguing trying to understand is all. Isn't the accumulator just pressure? Looks to be the same angle roughly as the jag, maybe a but flatter in the jag but its definitely not vertical.

    Most of the systems that use an accumulator like this are not mounted vertical, and inside is basically just a rubber bladder that gets expanded. Laying it over more should not affect anything. That being said the photo is a bit misleading, its not totally sideways, and the new brackets I am making are going to stand it up a bit more than my photo shows. It doesn't need to be as far over to clear the closeout panel.

    I would shim it to stand up as far as possible anyhow so it makes sense to make it as vertical as possible just for "good measure". :)

    If the cad plating would drive the cost up I am fine with the black coating too.

    coatings in small batches are VERY expensive..... I plan on powdercoating, there is always something to powdercoat anyhow. I suggest powdercoat then people can take it and do what they want from there. Even powercoataing will cost $30 per unit.

    ...Well, all I know is the horizontal mounting is not recommended by accumulator manufactures.

    I think the Accumulator being vertical is related to piston type Accumulator with seals that can dry, they want the valve at the bottom, not upside down so its not vertical per say its the valve at the bottom. I think.... I am not an expert here but if that's accurate the Teves set up is just a gas bulb, its a different type. Not sure if it his is correct or not, just guessing.

    Update on the Kits

    After endless research and hunting I have found an ACDelco part that should work for the pressure line. I am really excited about these because it will be a warranted off the shelf part and if there should ever be a problem can go straight to ACDelco direct.

    Banjo bolts are sourced and on their way

    I have sourced the reservoir feed line. This was also very difficult as the line can not be a general purpose fuel hose like all auto parts stores carry, it has to be rated to withstand the DOT3 and DOT4 brake fluid. I will be supplying a barbed hose connector fitting as well because the hose is almost impossible to get to under the reservoir, so the connector can be pushed into the existing hose and use the supplied hose and cut to fit the new length without removing the entire master cylinder unit. This is what I did on mine.

    And finally the most exciting part all the brackets will be getting yellow zinc plated to match the factory bracket.

    Again thanks to everyone who already purchased, and for your patients while I get these put together for you.

    Since we have some people with particular knowledge in this thread, I was wondering if anyone was familiar with the procedure for flushing/bleeding the brakes/abs with the Teves system.

    I did it once a few years ago but don’t remember the steps exactly.

    Something about pumping the pedal with the ignition off until it got rock hard. Then turning on the power and the pump runs building the pressure.

    Then stepping on the pedal and opening the caliper bleeder and the fluid comes out at high pressure.

    Something like that

    I used this method to flush/clear out some clogged lines/bleeders.

    Anyone know the actual procedure ?

    It's very simple if you don't get carried away with pressure/vacuum bleeders. Just turn on the ignition and let the ABS pump come up to pressure. Then pump up the braless, hold the pedal down and bleed each wheel as you would normally. Front brake fluid will be under pedal pressure. Rears will be under high pressure from the ABS system, so be careful on the rears as you crack the bleed valves. Fronts can be bleed with a pressure or vacuum bleeder, but rears need key on, pedal depressed.

    And of course, make sure to keep the reservoir full.

    Doing a little research and recognizing that accumulator bulb it appears my Porsche 993TT has a similar if not the same hydraulic boosted abs system as do all AWD 993 and any 2WD 993 with the ABD option.

    New pumps are still available from Porsche but prices have skyrocketed over the last few years to approx $4K new.


    Also, someone on the Porsche board successfully used a new jaguar pump motor as a donor to rebuild his pump motor.

    https://rennlist.com/forums/964-forum/1134959-c4-abs-booster-pump-unobtainable-rebuild-2.html#post15979911

    Finally new jag pump motors available here for $229

    That being said, what is the procedure to flush the fluid through the abs pump to avoid this issue. Is it the same as what is posted above?

    Is the Ferrari scan tool required to activate the abs?

    That connector on the pump completely foreign. It is also made offshore with questionable quality. The motor is not usually the issue it's the pump itself. The 348 does not have a scan tool it's not obd car.
