more disc brake questions
« on: July 28, 2005 - 02:34:27 AM »
Since I need front brakes really bad, and don't really have the cash for a $900 disc brake conversion kit.  I was wondering if I bought a set of factory disc brakes from another member on here,  what would it take to put them on my cuda? It has factory drums up front. Would they just swap out and bolt up?  Would it take additional parts?   Would the master cylinder have to be changed?   I'm not really a brake guy so sorry about all the questions.

if they are E body brakes the spindle will bolt on , you will need brake hoses , the master needs to be changed or the front doscs may drag all the time , also you need a proportioning valve to limit the rear brakes or they will lock when  hard stops are done

I just bolted a set on for my fathers 70 challenger... go to this link and read the models that work..
it cost us inder 200 bux for the whole shabooby..

find one of dem dare fmj body cars... thier a dime a dozen..
Now that you know what car your looking for the rest is easy...

ok - load the cars suspension and remove the upper bj from the spindle. unbolt the slindle from the lower bj - drums are gone!!
take the spindle from the donor car ( we used a 78 lebaron with longitudinal t-bars) and unbolt the lower ball joint - it;s a completely different design on your car, using your lower ball joint and your nuts and bolts ( the new bj is threaded) tighten it up and re install the upper bj into the new slindle, and your set.

I would take as much as I could from the donor car - porportioning valve ( needed to use the fittings from donor car on  3 of the 5 fittings, as they are different) master cyl, calipers,  ( cores only) and get 74 dart carliper, hoses, rotors, bearings, selas, master cyl, and pads)

ta da.... all done - now go beat it and you wont need 2 feet to stop it!

good luck - we did ours in a few hours, runnin to the parts store twice.. the motor was out so it made it easy to get to the lines, whick will be the hardest thing to get to if the motor is in there!

If I'm going from manual drum or discs to power discs, don't I have to drill new holes for the power booster? :dontknow: If I do have to drill new holes do I hook up the booster first then drill the holes?  If I wanted to use an old proportioning valve, is there a good chance that something could be wrong with it?
