I am having problems finding a peddle after replacing the rear brake caliper any tips?There is no pressure at the caliper end of the brake line. I have checked the master cylinder and it is pumping well.All was working fine until caliper casting failure.

Your vehicle should have rear drum brakes...They have to be adjusted manually for correct adjustment...People say they self adjust but it is not good enough....by adjusting the rear it will decrease the pressure on the front and deliver equal braking...This will help eliminate caliper pressure overload....I'm not saying that is your caliper problem but it is insult to injury and will save the life of front brakes.....Now your caliper problem..FYI..A rule of thumb is anytime you change a caliper you should always replace both calipers to have identical braking pressure".The same with brake hoses and rear wheel cylinders.....The caliper that froze in the first place got hot and boiled the brake fluid and quite possibly partially collapsed the caliper brake line/hose inside as Clint and Frank stated....I am going to guess that the first caliper froze under normal conditions however got hot enough to internally damage the caliper line/hose...Then you may think of the pressure regulator being bad in which case could be a problem......So this is what you do".Since we know the left front caliper line/hose has been exposed to heat it needs to be replaced anyway...also the fluid was boiled and it needs to be changed / bled...The new caliper that froze should be ok unless it was bad off the shelf which is rare but possible."..Change the line/hose,bleed the brake system and let the mechanic test drive before you pay and leave..The mechanic will know before driving if the new caliper that froze is bad or not by rotating the wheel...This is the cheapest way...And you will know if the pressure regulator is bad or not just by bleeding system........I hope this helps....."Brooks/Metalpoet....."....

I'd start by checking calipers make sure their not sticking

Hi Tommy, I'm glad to help! There are only 5 things that can cause brakes to hold: (1) Calipers are sticking. NOTE: There are several reasons calipers stick, there are internally frozen meaning you need new calipers. Here's how to check them release the nut that holds the hose to the caliper when the fluid bleed out and the calipers do not release pressure from the brakes then they are internally frozen, replace them. (2) Hose's are calapsed internally. You check the hoses in the same way, release the bolt and if the calipers DO Release pressure from the brakes then you know it's the hoses. (3) The actual metal lines going to the back of the Vehicle could be damaged. Example: One time one of the rear brakes would not release pressure and I found where the line goes acroos the rear axle something had hit the line and smashed it flat and so it was holding brake pressure on the wheel. (4) Let's not forget how much dirt and grime builds up on the brakes themselves. Example: I found one time where the LANDS where the brake shoes slide were so dirty that the brake pad itself was stuck and holding the brake pressure on that wheel. (5) The Master Cylinder, not very often, but I have seen the ports in the master cylinder clog-up and will not bleed back to release brake pressure. This is a few thing for you to check out that will help you find the problem yourself and save you money. Hope this helps and have an awesome day Tommy.

try adjusting the rear brakes up correctly
the spring that holds the shoes together pushes all the brake fluid back into the reservoir and each application has to move the shoes back into contact with the drum
that is enough to get the pedal close to the floor

THIS SHOULD BE A PARTS STORE PART, IT'S OVER 5 YEARS FROM PRODUCTION DATE AND AFTER MARKET PARTS SHOULD BE OUT THERE
BLEEDING THE BREAKS IS A TWO PERSON JOB , ONE WILL HAVE TO PUMP UP THE BREAK AND THE OTHER WILL BLEED THE AIR, SHOULD TAKE A 5/16 OR 3/8 WRENCH

The rear caliper piston has to be pushed and turned in, due to the emergency brake set up. There is a tool than can be used to turn the piston in, then press the piston in, then turn the piston again, until the piston is collapsed, you'll have to do this a few times, turn the piston clockwise. You might want to spray some WD-40 around the seal and piston to help turning the piston.

Sound like you've hit the nail on the head. Rebuild master cylinder with new seals, also rebuild rear caliper with new seals, check condition of pistons you may find that they also need replacing.

There's either a blockage inside the brake line or the master cylinder isn't working - or there is just too much air in the system to begin the bleeding process. Make sure you have drawn as much air from the system by applying vacuum to the bleeder valve on the caliper before expecting much to happen in terms of pressure.
For a basic check of the master cylinder, make sure it has brake fluid in the resivoir and disconnect the brake line from it, then carefully pump the brake lever (or pedal) to see if any pressure at all is being produced. If not, then overhaul or replace the master cylinder.

you will need to remove the brake line from the caliper, if the caliper will go back then you could possibly have a bad brake line. Also, you should open the reservoir when pushing the caliper back to allow the pressure to release. If the caliper does not go back, then you will need to either rebuild or replace the caliper.

hello rule of thumb never push pistons back on calipers without master cyl cover off pressure blows seal out on mastercylinder what you need do is from the firthest wheel pass rear bleed first then drivers rear then pass front to drivers side to mastercyl lines rear to front sounds like trapped air in proportioning valve with two people pump pedal up 3-4 hold take cover off master watch brake fluid take foot off brake pedal quick watch for air bubbles or small geiser like movement you need to work the air out reinstall cap repeat again if needed there shouldnt be any ripples when the peddle is let go if rear calipers have built in emergency brakes use emergency brake to wind caliper piston a few times goodluck
