I am using the stock Maverick 74-77 Disc Brake master with stock Maverick front discs and rear Crown Victoria discs. I retained the original drum/drum proportioning valve but added a Wilwood adjustable proportioning valve. I have yet to drive the car at any appreciable speed to test the adjustable proportioning valve, but it's there if I need it.
I have the factory disc/drum master setup with Crown Vic rear disc and it works fine. Actually there the '96 Grand Marquis variety. I see no need to add an adjustable valve.
A question for those who have converted to rear disk! Is there a significant improvement in braking performance over a disk/drum setup? I am questioning is it worth the effort?
Personally I think it is about the same. Could be because the front brakes are doing 80% of the braking
Thanks for the reply, wondering wud it be worth the effort. Probably going w/ 4 piston setup and larger rotor on front wud be more effective than changing out rear drums. That, combined w/ pwr booster setup will make serious improvement in braking..
I think that is a possibility! To much fr/rear braking on a 2 wheel vehicle wud be more of a problem. The probability of going w/ 4 piston cal. and adj. bias valve "if necessary", wud solve this problem. I had a car w/ 4 piston/ drum setup and worked fine.
then everything was designed to work together. 4 piston bore, rotor dia, prop valve and M/C bore. I would think you would need more front end weight (big block) to need 4 piston, big rotor disc. brakes up front on a Mav/Comet.
I have all wheel, disk on my comet gt and it makes a huge difference at higher speed if you ask me. I have the crown vic rears and factory up front BUT I went to a 99 ranger master cylinder and thats it. it has an amazing stopping improvement over my other comet that only has disk up front
Well, ur right, it was all designed to work together. But, u see aftermarket brake setups using 4 piston on earlier model Stangs, Camaros, etc. Think about all the mod's made to our cars that were not designed, that serve to improve driving pleasure/performance etc. You are probably one who has done, more mod's than most on this forum -- and seemingly, enjoyed the results a great deal. Correct me if I am wrong?
Good to know! I suppose it depends on -- Who you Ask. Hoping some others will convey their opinions/results on this topic.
