Gravity Bleeding Brakes

So when I owned my s2000, one of the techs on s2ki recommended gravity bleeding the brakes.

I had never heard of it, or ever heard anyone doing it. It's pretty simple. Make sure master cylinder reservoir is full, and crack the bleeder. Then let gravity do the rest, and just make sure the reservoir never runs dry.

Having said that, I have considered doing it on the TL. Anyone ever tied it? Thoughts?

It's simple, but takes time and you've got to be sure that the brake fluid is contained and doesn't contact the wheel. Personally, better off doing the job the more conventional way, hose in fluid push the brake pedal, have someone pump the brake, or use vacuum or power bleeder.

I don't see why you'd want to bleed the brakes unless you need to bleed the brakes. Know what I mean?
One way or another is good, although I'm also more of a conventional way person. That said, gravity bleeding does work and it's something you can do yourself while having a beer.

I only do gravity bleeding on my TL. its great when you have time to kill and don't have another helper. I'm pretty sure I've posted about it here on acurazine before somewhere.

Just changed out my brake fluid over the weekend and it was about an hour job total. I did have another person teaching me and having some nifty tools to get the job done quicker though.

Gravity bleed sounds like it'd take awhile, but at least could be done with one person.

Done it both with vacuum bleeder as well as assistant pumping. Assistant pumping was faster and easier IMO. Just don't have them push the pedal to the floor.

As for gravity process I've nothing against it other than it seem too slow for me.

I use my mity vac with a modified inline catch can so I don't have brake fluid all over my pump. Sucks it right out nicely.

Hey guys. Jumping cross forum here. I just did a gravity bleed on my 08 RDX while I changed out the pads. Thus I was able to push the pistons in and really get the extra fluid out. All the fluid in the reservoir is changed at the first wheel, then the other lines "cleared" very quickly. I thought the process was painless and simple, and brakes feel great. I honestly did not want to spend money on any type of bleeder.

I also come from the S2K community, where gravity bleeds are popular.
