Brake help

Last summer I replaced the d30 and d35 on my 89 YJ with a 79 F350 d60 front axel and a 88 GM 3500 14bolt. The 14 bolt has the disc brake conversion on it using 3/4 ton chevy rotors and calipers. Now I the problem of the master cylinder not pushing enough fluid to stop the vehical with out pumping the brake pedel a time or 2.

Does anyone know of a power brake booster or a different master cylinder I can put in to solve this?

Secondly I have no parking brake on the 14 bolt atm. What year and make do you suggest to snag a parking brake from in the local junk yard?

f350 m/c--early vette or merc marq if you have 4 wh disc. almost anything that bolts up and has 1 1/8- 1 1/4 bore..look into t/c e-brakes they work 100 times better and end up costing just alittle more.
 
For a proportioning valve look to the grand Cherokee.

Pushing that big of brake calipers I would look into going to a hydro boost style
that is powered from your power steering pump instead of the vacuum created by your motor. Summit Racing has these hydro boost brake parts for your jeep.
 

Thanks for the info and ideas. I will look into them and keep ya posted.
