Hi
I am a Norwegian Broncoowner with a new reardiscbrakekit from Toms Bronco.
After instaling there seems too be a problem with the rear calipers. After bleeding the system, the pedal needs too be operated a few tims before itv operates ok. It seems like the rearcalipers need more brakefluid than the mastersylinder can give. The first time the brakepedal is operated, it goes directly to the floor. Can anybody give me a godd adwise ???

Welcome to FSB.....

It mostly sounds like you've still got air trapped in the system. First make sure that there aren't any leaks. Check and double check. While you're looking for leaks, check for kinked line(s). If all looks good, bleed them some more.

Check this site for more info.

So what's the deal with the kit? What years does it cover? How much?

I would say air in lines still too. Need to bleed the brakes again. I'm also assuming you've verified you have no leaks. The master should be just fine. I put chevy K20 rotors and calipers at all four corners and have had wonderful braking with the stock '95 bronco master cylinder, and no added proportioning valve.

Are the calipers off a caddy? if so, do you have the e-brake set up on it?
Or do you know what the calipers are off of?
Have you adjusted them up by operating the e-brake a few times?

If the rear caliper piston is too far from the rotor it will feel just like air in the system, and it will take a couple pumps to get your pressure back.

did u gravity bleed the brakes or use a vacuum system? all i can say is you got air in the system.. if he had a leak to make the brakes go to the floor u would see it in no time flat.. thats out.. ive done brakes for years and ive noticed when your putting new calipers on a vehicle sometimes it takes forever to get the air out... one day it took me two hours to do rear calipers on an old corvette.. do to air in the system.. bleed bleed and re-bleed.. if u still cant the air may be caught up near the resevoir.. get a buddy to sit in the car while u barely crack the lines on the master cylinder and slowly pump the brakes sometime the air will escape thats trapped near the master cylinder.. thats how i got the corvette rear calipers(4 piston) bled and had an awesome brake pedal .. give that a whirl and see if it helps.. but you always have to pump the brake pedal after doing brakes ive seen some try and back out of a garage without pumping them and ya should see how big there eyes get lol..
