A while back my front passanger brake kept locking up. The vehicle is from 89 so I know all the shit down there is old. I pulled it apart and noticed the inside pad was demolished. So I replaced the pads but now I never have any brake pressure till the very bottom of the floor and the fluid always goes low as soon as I step on the brakes for the first time after refilling it with brake fluid. Is there any possibility I could have damaged the master cylinder or the brake booster and thats why my brakes are all screwed up now? There is always tension on the front right brake since I guess there is not enough pressure in the line to pull it out. Any suggestions?

 

I dont quite understand your exact question due to your writing but I'll try to help you. usually if your brakes are grabbing on one side the caliper is sticking. I would try to push the piston of that particular caliper back in and make sure it goes in smoothly. If its stuck I would replace the calipers. If you only did a pad slap then I dont believe its even possible to hurt the mastercylinder or brake booster from a pad slap. i dont know how you would do that. If you didnt crack any lines open when you did a pad slap then your fluid problem lies elsewhere. If its got drum brakes i would pull the drum of and check to see if the wheel cylinder is leaking, this is common leak spot. Also check to see if your brake booster shows any signs of brake fluid going into it. Usually if that happens it will damage it and you will get a hard pedal from the vacuum assist not working properly. If you get fluid in the brake booster you should replace it as well as the master cylinder since its obviously leaking. If all those check out make sure all your lines are tight and go back and bleed your brakes starting with the passenger side rear, then driver side rear, then passenger side front, then driver front last. You shouldnt be getting a leak from under the car since those should be metal lines. I hope this helps, if not give me a little more description and ill try to help further.
