Anyone have a T90P-50-ALA ABS Tool?

A friend of mine has a pretty nice 93 mark. While doing the brakes one of the rear lines snapped because it was rusted to the flare nut. While it sat overnight until the parts store opened to we could buy unions and flare nuts, all of the fluid drained from the system. The old line was cut back until it was in good condition, the new line was spliced in and connected to the new flex hose and caliper. This car has all new brake components in the rear and a 1 year old cobra brake upgrade in the front.

After helping him flush 3 quarts of new fluid through the system while bleeding it in the front and back multiple times, the brakes just are not firming up like they were. The system has been checked for leaks thoroughly, none found. I also checked brake line pressure with a rotunda brake pressure gauge I have, appears to be ok. The car is drivable but the brakes are spongy as hell.

We suspect the issue is some air may have gotten into the ABS pump. I have MANY Rotunda tools from a dealership I helped liquidate but I don't have the T90P-50-ALA tool that is needed to activate the ABS pump and open the valves for 20-60 seconds. Does anyone have one they would be willing to rent or sell?

It looks like this:

You may be able to do it with some aftermarket scanners. I know my snap on mt2500 (old POS) can do the ABS bleed procedure on newer fords, although I am not so sure about the older ones. If you have a friend that works at a shop, I would ask them.

The only other tool that will work on this ABS system is the Thexton 133 tool which doesn't seem to be available either. Later model cars let you use a scan tool over the obd 2 system.

But I was able to locate the rotunda tool, it should arrive next week.

Disregard this if you know already but when I bled my brakes I was surprised that with ABS brakes the rear has to be bled with the ignition ON. I had the same problem until I figured that out. Unless you removed something that's directly attached to the ABS pump there shouldn't be any reason to use that tool. The ABS system will prime itself and remove any air while driving. Now if you did remove the ABS pump that would be another issue.

If you get one of those, make sure to hook a charger to the battery whiule using it. the ABS pumps draw a decent amount.
I've got one, but think shipping would be quite high across the border each way They are great when I do the brake flush every couple years as then I know all the fluid is changed...

Yes, thanks for the info but from what I can see the mark and t bird abs system has differences. I don't believe the marks system does what you described. I've worked on and bled the brakes on marks more times than I can count and never had this issue. I also have never had the system drip overnight due to a damaged line. The car with the issue has been driven quite a few miles with the brakes like this and bled on two separate occasions with no change. This is more or less the last reasonable option we can see. I'll update this week after using this tool and another full bleed.

Also was there something in a factory service manual about bleeding the rears with the ignition on? The mark factory service makes no mention of this but the tool i bought is mentioned quite a few times.

Update, I found a tool and bought it. Used it and all kinds of milky looking fluid was purged into the lines with some air. This WAS NOT in the lines before running the pump with this tool, the system was bled with 2-3 large containers of fluid twice before this trying to correct the problem. Now after running the pump all the crap it out of there. The brakes catch right at the top now, never been better!!

If anyone needs it I will have the tool available for rent, I want to keep the tool, but I know they are hard to find and want it to be available for other people that were in the same position as me.

FYI I used this tool to bleed my brakes and purge the ABS system. I wrote an article with photos on the process here: http://www.mn12tech.com/brake-fluid.php

Well.....can't say for sure. But I can tell you my friend got some air in his abs system when one of his brake line rusted out. No matter how much fluid we put through the new lines, we could not get a firm pedal. The brakes worked, but not well. Once I did some reading and picked up this tool we gave it a try on his car. Sure enough once we were finished with it the brakes were nice and firm like they were supposed to be. We did try to activate the ABS system by going over a dirt road at about 30 mph and hitting the brakes. While it did activate the ABS it didn't do anything to purge the air from the pump.

If you can't get your hands on the tool, you could pay the dealer to do the air purge process. I believe that specific tool is out-dated now, I think they can do that with their big magical scan tools that plug into the OBD port...??

Don't however, trust a brake or independent shop to get the job done. The brakes on my car were "flushed" by a small brake shop in town (I got the receipt from the previous owner). BS, the fluid was black, there was air in the lines, the pedal is much better since I bought the tool and used it to purge air from the ABS controller thingy.

I actually own a brand new one. Cost me a pretty penny but I'm getting ready to swap my front calibers and master Cylinder and fix my ABS. Then completely flush the system. I might be willing to rent this out for 20 dollars but there will easily be a 300 dollar core charge that will be refunded when I get it back. Too many thieves in this world now adays.

Funk,

Still willing to rent that T90P-50-ALA? I can't find one anywhere and I need to do some brake work on my Cougar. Looking to get some stainless lines, 13" rotors and calipers, and flush the fluid.

Let me know if you are interested.

Thanks,

Pete

Absolute worst case scenario, is bypassing this system a viable option? I only ask because I did pick up a later Bird, and I'm going to try to drive it a while.

Just sayin'.

So yeah, I bought two Lincolns in a week.

You will never get a good tight pedal without using this tool. I bought one myself. One minute and it made all the difference in the world.

Good Luck,

I don't think it is all that easy. Best to find one on ebay. I payed 200 bucks for mine but it was well worth it the rip off.
