01 ranger brakes dragging when released, is there a spring in the master cylinder that's worn out?

I would start by replacing the rubber lines, they may look okay on the outside but be worn out on the inside.

Buy the repair guide for your automobile. I depart the cap off the master cylinder and i have an assistant or two. One person pumps the brake pedal, the opposite opens and closes the bleed valve even as telling the individual doing the pumping when to press and when to liberate the brake pedal (liberate after closing the bleed nipple). If there's a 0.33 character, he/she can be retaining a watch on the brake fluid level in the master cylinder reservoir - and topping up as quintessential. If the level of fluid in the reservoir drops too low, it should allow air into the approach and you can have to everywhere once more. As for the order of bleeding the brakes, that relies on the auto. Some cars have twin diagonal circuits, some are dual entrance/rear. Some automobiles have ABS and a few do not. Particularly customarily, the order is establishing with the wheel with the finest distance of brake line and dealing gradually to the wheel with the shortest brake line (whole, from wheel cylinder to the grasp cylinder). I've visible ABS models with a bleed nipple (or nipples) on them too. Assess the repair guide for detailed small print related to order of bleeding the brakes, and so forth. ><>
