Brakes have failed, mech cant help Reply #15 – April 18, 2013, 11:14:15 PM I gotta agree that the ABS setup on these cars is nothing but trouble with the way it's designed, and you'd be better off ditching it, but if a mechanic is doing all your work, it might be a little expensive to pay him to convert over to Vac-Assist as there is some slight modification and parts hunting involved. Will be much cheaper to just get him to throw in another ABS unit, as that is something that he can just bolt-on and plug-in. It all depends on what your end goals and budget are really.

Brakes have failed, mech cant help Reply #17 – April 19, 2013, 06:51:18 AM That line setup is for converting for the master!!The ABS setup on the TC is GARBAGE. But the booster is not. The systems are basically separate. But trying to fix the unit at hand might be a simple wiring issue or bad relay. Either you or your mechanic will have to do some troubleshooting. But it sounds like your mechanic does not know the system. So you have to go to plan B or C.A fix the existing unitB Convert itC Get a mechanic that knows how to trouble shoot the system!!Just for the record the location of the PUMP relay is NOT IN THE TRUNK !!!!!!!!!!!!!!!!Hydraulic Pump Brake Motor Relay (Anti-Lock Brakes):LOCATION Cowl TopJust some thoughts if i may!!!!!The ABS system is basically separate from the BOOSTER.The BOOSTER is self contained and Needs a battery feed to and from the relay. Check the relay properly and try running the pump motor. I have never seen a pump motor go bad. But that means nothing it has to be checked. So check the relay and the pump motor and fuse link S,NOTE the 1987 shows fuse link C I think this is a miss print. Either way check the fuse links at the starter solenoid!!! Quote Selected
Brakes have failed, mech cant help Reply #18 – April 19, 2013, 10:49:16 AM Personally, I like the electric booster set-up. The early ABS systems all suck, but I did enjoy the consistent feel of the electric booster in my Scorpio, which is the same set-up, basically.If I was bored, I might consider a booster swap into the TBird. However, I have MANY other things to do instead of that.IMO, the OP should diagnose what's actually wrong first, then decide if he should consider the vac-assist swap. Quote Selected
Brakes have failed, mech cant help Reply #19 – April 20, 2013, 07:27:46 AM Another PLUS of converting to VACUUM is the ability to use a SPUN UPPER. That is a BIG BIG BIG PLUS. So at this point you might want to do the conversion and call it a DAY. Just saying!!! Quote Selected

Brakes have failed, mech cant help Reply #21 – April 22, 2013, 06:00:27 PM That is the ABS section. The electric booster can still be GOOD.A spun upper is turned 90* so it faces directly forward. Quote Selected

Brakes have failed, mech cant help Reply #24 – April 24, 2013, 06:17:58 PM Being serious though, the Teves unit is pretty heavy so you might lose a little weight. It is also a pain to remove as the nuts under the dash are kind of tough to get to. Quote Selected
Brakes have failed, mech cant help Reply #25 – April 24, 2013, 08:21:32 PM Use a 3' extension and a swivel. Remove the drivers seat and you are good to go!! Quote Selected

Brakes have failed, mech cant help Reply #27 – April 25, 2013, 08:58:26 AM I had an easy time removing the brake booster, don't know what all the fuss people have put up there was about. With the drivers seat out, and the right tools on hand, I had mine out in 20 minutes. The TEVES ABS unit is not really heavy at all, unless you consider 15lbs heavy. Honestly the hardest part is swapping out the brake pedal for the correct non-ABS pedal, and modifying the brake lines to fit the SVO MC. The stock ABS brake pedal will work with the Vac-Booster, but you won't have quite the braking action that you should have without the correct non-ABS vac boost brake pedal installed. I believe MM sells a kit to connect the stock prop to the SVO MC, as well. Once you have all the parts on hand, it shouldn't take you more than a leisurely evening to get fully done. Quote Selected
