I just changed the rear brake pads, rotors and calipers. The brakes will not bleed, they are getting little fluid thru them. The pistons on the calipers will not tighten up either. The pedal is not tigyhtening up either, i can push it in with no problems. Is there something wrong with my master cylinder???

Check the lines right by the calipers. My blazer's lines got clogged with something that wouldn't let the brakes bleed.

Let's check a few things first before you spend a lot of money. Be sure your brake fluid reservoir is full of the approved brake fluid. Does the caliper on the other side appear to be working? Completely remove the bleeder screw and plan to replace with a new one. Do you have brake fluid? If not remove the brake line from the caliper and see if anything comes out. If not, remove the hose from the brake line anchor near your rear wheel occasionally crap gets lodged inside the brake hoses. Does there appear to be fluid at the brake line? If you have fluid at your lines and the caliper is working on the opposite side it appears you need a rebuilt caliper.
If you have no brake pressure anywhere then think about a new master cylinder

ABS pump could desire to be going out or a ABS sensor on the perfect front could desire to be sending a sign to the ABS equipment to persist with braking potential to that section and the pads get too warm. Take a force for countless miles with the brakes chilly and attempt to no longer use them lots and are available to a mushy supply up. heavily sense around each and every wheel assembly searching for a wheel it extremely is a lot warmer than all the rest. One warm wheel might mean that that brake has been dragging and burning out your new pads. in case you place your palms on the rotor you will get burned so be careful around those aspects. A dragging caliper could be a bad grasp cylinder, ABS pump, proportioning valve and so on. or an inclination or pinched brake line. Brake fluid will bypass one way under pressure at the same time as braking yet then has a no longer person-friendly time flowing back contained in direction of the limit

Make sure that the bleed nipples are not blocked--clean with a thin wire--if your brakes were ok before you did the work then it is unlikely that the master cyl is faulty .Start by bleeding furtherest away from the master cyl and with an assistant pressing the brake pedal open the bleeder and put your finger over the bleed hole.get your assistant to pump away and remove your finger occasionaly and putting it straight back until pressure builds up.Make sure the master cyl doesnt run dry of fluid

check the proportioning valve
