cmayna - aren't you are getting ready to do a paint job? I have just picked up all new wheel cylinders and a master cylinder and three new flex hoses and am waiting for Rugo to order his new stainless brake lines so we can get a qty discount and the total bill will be much less than it would cost to straighten an AD grill not to mention the rear end of just about any car.
If you are going to invest in your truck, brakes are about the best investment you can make. If your fluid is mucky looking, no doubt it has a lot of moisture in it and you have corrosion in your lines and cylinders.
