my 2005 accord has 232000 klm and just replaced the rear rotors,pads and calipers I have bled the lines and there is lots of fluid but hardly any fluid pressure to rear calipers I have to pump the brakes to get what feels like a full pedal if I dont pump the pedal goes to the floor and I get the front brake or brakes doing all the work.Any suggestions

 

More bleeding. Unless you're getting a pure brake fluid stream w/ no popping or burping, there's still air in there. It may take more bleeding to remove trapped air from new calipers.

good luck

 

Is the bleeder valve pointing up on the rear calipers, or pointing down?

 

I don't recall right now.What does that tell you?

 

It might be possible to switch the driver and passenger side rear caliper. You can definitely do that on the front calipers.

Switching the calipers and having the bleeder valve pointing down on the bottom of the caliper would not allow air to bleed from the system.

Someone had a thread on here about front caliper replacement and the person couldn't get pressure on the brakes. It took a while to figure out that one.

 

I kind of knew where PAHonda was going with this, as I was suspecting it might be possible. I don't know if it is possible on your car though.

It has occurred before for people on other makes of car, it makes it very difficult to bleed all the air out if this happened, a small pocket of air remains in a portion of the caliper when this happens. There's even a youtube video of a shop have a tough time with a sinking brake pedal for an old Dodge Charger (General Lee), they finally bleed the air out; but, not before doing a lot of different bleeding procedures (e.g., reverse bleeding, etc. that did not help.) They eventually got the air out by hanging the caliper, using a block of wood between the caliper so the piston doesn't close all the way, and then bleeding.) A lot of the people commenting on that video said the the shop still didn't even know the calipers were switched around.
