Gravity bleeding on 2004 WJ
 
I have seen several very favorable opinions on some Chrysler and Dodge forums for the gravity bleeding method on brakes. Has anybody done this with a 2003 or 2004 WJ? I know it is slow - but apparently a very thorough (and safe) way to flush out the entire line to each wheel.

Thanks for any advice...

Why are you trying to gravity bleed the brakes?

Well, this month it is very simple. I have just laid out $800.00 basically replacing all components on my A/C system and another $600.00 on my wife's car - and all of this took place in May. So I don't want to spend another $70.00 on a Craftman vacuum bleeder at this time.

From some of the write-ups I have seen, it is the easiest (and slowest) way to bleed your brakes if you don't have a vacuum bleed system or you don't want to hassle with the two person pump and bleed method.

True, I really haven't heard of the gravity method but it sounds like it wouldn't hurt to try

I've heard of the gravity bleed method. They claim it's the safest. They say that if you pump the brakes, you can push the master cylinder too far and cause corrosion to enter the brake lines. On all the cars I've owned, they've lasted into high mileage (200k miles). I've bled all the brakes with the pump method and never had an issue. I have a "speed bleeder" that makes it a 1 person job (it's a check valve) and I'll continue to use this method.

If you have hours to let your brakes drip, then it's that simple. Unhook the lines, remove the cap on the brake resovour, and wait. I'm not that patient.

I have used the gravity bleed procedure and it didn't take that long. As long as the fluid was changed every 2 years, there is a very remote change of corrosion buildup in master cylinder or other parts. If there would be some residue in the master cylinder, then there is a change that it would displace when putting the brake pedal until the floor and it could cause problems in the very small openings of the ABS valves.
So i let it bleed out until the reservoir is almost empty, fill it again and continue bleeding until fresh fluid comes out of the bleed screw. But don't let the reservoir become empty, otherwise you have to the bleed the system for air.

Thanks for the reply...I may just wait and spend the $70.00 out of next months budget and be done with it.

Chris I got my vacuum bleeder from Harbor Freight and wouldn't live without it now. You're just paying for a name at Sears. http://www.harborfreight.com/automot...kit-92474.html

Hi Dave, thanks for the link. I got a Harbor Freight location about 2 miles from the house. I will check it out...appreciate the tip!

On my 04 Laredo I could not get any fluid to come out when I changed the left rear caliper.. I have a hand held bleeder and it did not work. When the hose was off no fluid came out. I put it back together and took it to a local shop. The mechanic opened the right rear bleeder valve out came fluid. He did all four and refilled the mc. Turned out before he bled the calipers he LEFT THE MC CAP OFF.
