Bleed your brakes!

Bleed your brakes!
There are a few people who think that you really don't need to bleed your brakes that often to keep things okay. Even if the car has only 25k miles or less on it, they think that all will be okay. It's been mentioned many times by a number of people on this web site that brake fluid is hygroscopic (which means it absorbs water) and that can eventually cause problems with the brake system. Well here are a couple of examples of someone who thought that they didn't need to bleed there brakes very often because they hardly use the car. Below is the result of not bleeding your brakes for 5 years with only 6k miles. The next time they went out and used the brakes, major leaks on both front calipers. Don't be stupid and cheap when it comes to bleeding your brakes. Do it yearly or more often if you track the car or abuse your brake system. Also high heat temps on any brake fluid will create bubbles in the fluid in the caliper and brake lines which makes them feel spongy. Do it! It just may save your life some day.

Well for the average mechanic who may or may not have a buddy to help, I would recommend using speed bleeders from Russel's to make it a one man operation without reintroducing air back into the caliper. You'll have to measure the size of the thread and pitch when you order them from their web site. I haven't done that on my "G" yet but I have on my NSX. Works great especially in the field when you're tracking the car and must remove any heat induced bubbles in the system. If you have a compressed air system in your home garage, then you can buy a inexpensive suction device which will pull the brake fluid through the caliper through the bleeders as you keep filling the master cylinder. There is also a system which you fill a special container, hook up the hose on the special cap for the master cylinder, pump up the container and that pressure bleeds the fluid throughout the system. All work great and it's not rocket science here. If you've never done it before, have a good friend/mechanic show you and from there buy the right tools and go for it.

blnewt,
Just why is the sequence so critical? I always work from the master cylinder to the farthest caliper and work my way to the front. Since we don't have any power on the system, why should it matter which caliper gets bled when it does? Just curious.

How do you know when you've pumped all the old fluid through? That is, how do you know if you've flushed the system?
I bled my brakes once, and just made sure the fluid coming out was clear, roughly ~3 pumps per bleeder.
