Master Cylinder Replacement
I may need to replace my master cylinder in my 96 bronco. I have performed a full brake job (pads, shoes, calipers, pistons, drums, rotors) on my old 88' F150 but have never tackled a master cylinder replacement. I would consider myself of average mechanical skill. Am I getting in over my head? My only real concern is messing up the ABS system.

Sounds like you have some mechanical knowledge and experience. The master cylinder is not a hard job at all. Be sure to use penetrate fluid of your choice on the brake lines to keep from twisting them. Just curious what the brakes are doing to make you think the master cylinder is bad? I'm sure you have a shop manual of some sort and that will give you guidance. The new master cylinder will have a set of fluid bleeding instructions with it (follow them). I've always had to bleed the whole system after I removed the master cylinder. Some people disagree but I've never had such luck.

I think that air is getting into the lines somewhere causing a slight loss in pressure. I am going to pull the tires and inspect the entire system today.

Check to make sure you have no leaks. Just look under your Bronco and check the axels. If you have a leak you will see the fluid marks on the axle. The master cylinder if it is scored, will cause you a return problem as well. If your master cylinder is bad and causing air to get in your system then you will see some brake fluid leaking around the master cylinder. It's nothing that I don't think you wouldn't be able to handle on your own.
