After bleeding calipers did you refill the brake fluid reservoir all the way AFTER you pumped the brakes? Have to pump the brakes and keep filling until full.

 

 

ARE YOUR BLEEDERS ON THE TOP OR BOTTOM?
Oops caps were on!

 

How are the brake lines? I'm assuming they're rubber. Do they feel or look a little old? Pinch a line with your finger and see how easy it is to do. If the lines seem a little soft then they could be losing pressure when you step on the brake. I know a lot of people will replace brake lines on motorcycles to braided steel lines becasue their brakes are too soft.

 

Front bleeders are up. Rears are down. Replaced 1 rubber line on the drivers rear. All others are original. Will pinch check them.

 

Your rears are wrong. They have to be on top. you will never bleed them.
One of them belongs on the other side.
The other is wrong.

 

 

You're not the only one!

If you're in a pinch and have to drive it before you can get the new calipers you can take those off, and stick a clock of wood in them. Then you can position the bleeder on top and bleed the air out. Not ideal but it'll work

 

All he did was put the right on the left and the left on the right. Go buy new brass washers and flip the rear calipers to opposite sides. Then bleed the brakes again, start rear right then Rear left he front right and finally front left

 

 

I think you have probably fixed your swish brake pedal. FWIW I have replaced probably 10 calipers on my truck. I really think you need to do brake lines anytime you do the calipers. Since I started doing that and brake fluid flushes with tire rotation, no more new calipers. Also stainless braided brake hose seems a worthwhile upgrade - those are the one I used the last time.

 

Done. Not perfect. Back to normal. Replacing rubber lines may help. Major appreciation for all the great insight. Y’alls the best!!!!😁
