After swapping in my new axles and doing a 14bff disc swap, I was left with barely a brake pedal. Common problem I know. So I tried a new master for my blazer, it helped some. So I did some research on here.

I know I have the JB7 calipers on the rear, and my standard 1/2 calipers on the front. So I decided to go with the JB7 MC for starters. It helped the pedal a lot, but it still won't lock anything up like others have stated.


One thing I did not like was swapping the front and rear lines because of the different sizes. I ordered a 79 K-20 MC, and it's bolted onto a 79 K-5 booster. Strange thing, the smaller reserve is on the front and the bigger one on the back of this master. Is this normal to be swapping the front and rear lines on these MC's?
