    I finally got my eldorado calipers for my 14bff swap today. I am planning on installing them tomorrow and have a few last questions. From what I understand there is some sort of a check valve that maintains a few pounds of pressure in the lines for the factory rear drums. This is located in the master cylinder right? I would imagine this should be removed, can anyone tell me where to find it, and how to get to it and remove it? Oh, and the truck is an '89 Jimmy. I was also wondering if I am going to need an adjustable proportioning valve, or am I ok without one? And the last question I have is about the e-brake. Do you guys just use the stock e-brake cables to run the ones on the caddy callipers? Anyone got pics of their setups? Thanks in advance for any help!

    You do not need to remove anything from the system nor do you need to modify anything other than adding your rear disc set-up. I used my factory e-brake cables. Here are a couple pics of my set-up on my 89 blazer.

    so then, does your pedal feel firm or does it go to the floor like others have been having problems with?

    My pedal is firm and works just as it did when i had rear drum brakes but the only difference now is that i can stop on a dime.

    I've been running my rear disc now for about 4 years without a single problem.

    That is good news, it will make the job that much easier. Thanks for the info, and the pics. I can not view the pictures though, I think I need to update my membership, I have been away from ck5 and my own k5 for a long time. Thanks again.

    my ebrake is for show... well at least it was last time I went through inspection....

    It doesnt work great but the brakes stop alot better... I had problems with the drums and these suckers are nice......

    I need to make better brackets for my ebrake as all I did was run the lines under and leave them under the axle.... not the greatest....but it does work sort of....

    I was playing in a cranberry bogg so there is all kinds of grass in the brakes :haha:

    Your bracket and springs are from the eldo calipers and mine are from fleetwood and seville calipers. My calipers are eldo but nothing else. It is way too hard to find the eldo hardware but super easy to find the fleetwood and seville hardware.
