Fixed broken caliper on 88 toyota 4×4, now no brakes?

I bough a 1988 toyota pickup 4×4, and the previous owner broke off a bolt connected to the front caliper (Split the caliper when taking it off), so we fixed the broken bolt and put it back together and now I have no brakes, it goes straight to the floor.

Bled the brakes, front only, rear drivers isnt hooked up.

Didnt touch anything else.

Any idea’s? Master cylinder, but why would it just go out all of a sudden?

Thanks.

    When he broke the bolt, you split the caliper, but then put it together without getting a new caliper? If that is the case, then obviously you need a new caliper. My bet would be to check the caliper and lines on that side (both to be sure, but especially that side) and make sure fluid isn’t leaking out anywhere. If you didn’t get a new caliper, you should get one.

    Perhaps you’re bleeding it wrong. Did you take the caliper off? or the piston out at all?

    Too much air in the system to build pressure… bleed the system backwards from the caliper up to the master cyl… get one of those oil cans that have the little pump handle, clean it out and put clean brake fluid in it, then add a small piece of hose to the tip of the can and hook it up to the bleeder on the caliper… crack the bleeder open about a half turn and start pumping the brake fluid thru the caliper up to the master… then close the bleeder once the level in the master cyl resevoir starts to rise… and step on the brake and you should have brakes…. good luck

    What do you mean "Rear Driver’s isn’t hooked up!?" Everything has to be bleed for the system to work right! if you have "One Brake" Not Hooked Up, 1; is going to pull hard to one side! 2; Brakes aren’t going to work!

    NOTE; "Good Brake Shop" to check the system NOW!!!
