I recently painted my calipers, and when I took them off, all of the fluid drained out of my brake lines. The rear brake bled with no problem, and after just a few times, the air was out of the system. The front brakes however are a problem.

We have started bleeding the brakes, but after an hour, there still isn't any pressure when you pull the lever down. We have bled from both calipers up front, and still the level just goes straight down with no resistance. We weren't sure if it mattered which caliper we started with, but it didn't seem to make a difference. I guess basically I am asking does it sound right to have to bleed these for this long? Or does there seem to be something funny about this?

Thanks.

 

I guess I should have said that fluid is coming out of the calipers when we open the bleeder screw, along with some air bubbles. And we don't see any leaks in the system.

 

Invest in some speed bleeders, they make the job a lot easier. If you have no pressure there's still air in the system. Have you bleed at the master cylinder? If not, that may be the problem. Bleed from the caliper furthest from the MC(left) then do the right caliper and lastly the MC. That should do the trick.

If you're still having trouble, use a vac system to get the air out. You can get one at any PepBoys or AutoZone for around $20. As you're vacuuming out the fluid/air make sure you're adding new fluid to the reservoir to compensate for what you're pulling out. DO NOT let the reservoir go dry, if you do you have to start the process over because you just pulled air into the system. It may help to have a friend keep an eye on the reservoir and add fluid as you're vacuuming it out.

Once you do all of that, you should have pressure at the lever...take a zip tie and put it around the lever and grip as if you were braking hard....leave it like this over night. Tomorrow morning the lever should feel very hard. Best of luck.

 

How exactly do you bleed from the master cylinder? Do speed bleeders just fit into the spots where the stock bleeders are?

 

this happend to me on my buddies r6, i thought it was never gonna work. all u have to do is bleed the master, just loosen the banjo bolt like you do the bleeder valves. it makes a mess but works. also tap on the master cylinder-not too hard, but it helps break up the air bubbles

 

My RR has a bleeder at the master. Yes, the speed bleeders will replace your OEM bleeder.

 

Thanks a lot guys. I bled at the master cylinder, and almost instantly the system had pressure. Amazing.

 

Good deal, do the zip tie trick like I said and you'll love the feel even more.
