No brake line pressure on 1 caliper after replacing caliper
I changed the caliper on the front driver side an then rehn tried to build pressure an there is no sign of an brake fluid even trying to go to the brake caliper. the passsenger side front has fuild running when i check the bleeder screw. i'm stumped.

Re: no brake line pressure on 1 caliper after replacing...
I suspect you may have twisted the hose on re assembly. The other possibility is that the bleed nipple is choked with dirt and rust. Remove it completely and see if the fluid starts to run out. If so replace nipple or clean out.

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.
Are there two brake fluid reservoirs? And are both full? This would be a split-diagonal brake system-front driver and rear passenger are one brake system. Front passenger and rear driver are the other system. You have the one system working-the front passenger and rear driver side works. You will have to keep bleeding the rear passenger side and the front driver side-always start farthest from the master cylinder, but if that wheel just won't bleed air out, make sure the driver front is working and bleeds good. If all else fails, there are pressure bleeder kits available, I don't know the cost, but they work great. They are also a one man bleeding job, as I understand.
its either the caliper or the brake line remove the caliper and try to squeeze the piston in with a c clamp if its tight its bad also remove the brake hose and blow through it they implode inside the fluid goes through the tight spot and builds pressure and applies the brakes on that wheel
Something doesn't sound right, you shouldn't have to remove the brake line to install pads. Did you have to do this on both sides? Do the new pads and the old pads look the same? Did you get the caliper on crooked? Just recheck your work first before replacing more parts. When you install the caliper, You have to hook the pad on one side first before you slide it over the rotor.
okay did you pressure test your brakes??? jack up front have some one press pedal try to turn wheel then when pedal is released tire should turn if not wait 1-2 minutes then try to turn the wheel with no body pressing the pedal and if it does turn then I would be replacing flex hose!!! fact: if caliper is seized it will not turn !these flex hoses build rust under the steel fastener bracket that is moulded around the hose then slowly over times closes it off as rust builds and slowly closes it off to a pin hole passage i have changed thousands of these over the years! yours will probably be the same! brake fluid has no problem making it to the caliper and bleeder it is when you release the brake the applied pressure is gone and now it take a couple of minute or seconds to slowly return!!!!! I know this will help!!!!
Probably a restriction in the brake line from the master cylinder to the wheel.
Most of the time brake hoses do this (collapsed hose or hose inner liner) but the restriction could be anywhere from the point your front brake pressure divides to both wheels to the caliper of the wheel. The problem is not the caliper itself because the bleeder is able to relieve the pressure.
