Have a 1992 400 and I installed new front steel lines, turned the rotors and put on new pads yesterday. I went to reinstall everything and I cant seem to get all the air out of the system. I have been doing this for over 2 hours to get all of the air out. I bled in this order, LR, RR, RF, LF, and there is no bubbles that I can see coming from my clear hose from the calipers. I have NEVER had this much trouble doing a simple brake job.

I got on here and did some research and someone stated that I may have the front calipers backwards or upside down. Is this possible? Would this be the cause of the spongy, to the floor brakes? Has anyone posted a DIY on doing the proper way to bleed brakes. Any help, and I would appreciate it. I need to get this fixed in the morning.

 

Since I had no responses and more hours of bleeding. I still have no sign of leaks and still have a spongy brake pedal. Off to the shop this morning. Its prolly something stupid that I have done. I have never, and I mean never had this must trouble bleeding brakes.

 

I just got it out of the shop and the mechanic stated that I had the calipers backwards, in other words the nipple point was facing downward. I guess I had a brain fart when I resprayed them and took them loose. What a freaking headache. So word to the wise, pay attention.. and the front calipers can be put on the different sides and bolt right up.

 

yeah paying attention when you work on car...who would have thought its a necessity :-P JK

yeah the calipers can definitely be flipped sides.

 

I almost did the same thing. Thankfully, I got in the habit of using my digital camera everytime I take something off my car. I use the pics as insurance and refer to them before I start to reassemble.
Since I've started this practice, I NEVER have spare bolts/nuts/washers when I finish a job anymore! LOL
