How often should your cars' brakes be bled?

Question

Thanks guys!

I think I got a little air bubble yesterday, but after checking the brake fluid and pumping the brake for a couple of minutes all was fine...? Might get it done to save the hassle of not having brakes again.

;o)

Answer 1

Hi

The brake fluid should be changed completely every two years regardless of mileage or condition which obviously consists of a full bleed through.

As for simple bleeding, it shouldn't need to be done unless you get air in your brakes, in which case there is a problem such as a leaking caliper, cylinder, hose, pipe etc..., which will need to be repaired beforehand anyhow.

Brake fluid does absorb moisture over time and the moisture then evaporates due to the heat created during braking, and can create spongy brakes, but by then the fluid will need a change so you're at the "every two years" scenario above.

If you are having problems with your brakes then mail me and I'll help you out.

Flush the lines with new fluid at least every 5 years. People who say to never change it have obviously never seen the junk that the old fluid turns into with time. If you're using fluid, you have a leak and need to find it and fix it. A little fluid over the years is ok, because you have to add some as the pads and shoes wear.

Answer 3

Brake fluid is hydroscopic and as such will absorb moisture.

When moisture is in the fliud, it can gas at high temperatures, or pressures, resulting in soft braking.

This is the main reason for changing your brake fliud every two years.

You would always bleed the system when replacing the fluid or making any repairs on the braking system.

Answer 4

Most manufacturesrs suggest changing the brake fluid every two years. If you are continually having to bleed then change the fluid and if that doesn't solve it then you need a qualified mechanic to look at other possibilities.

Answer 5

Only when one of the hydraulic brake components was replaced or disconnected. Believe it or not, air works it's way up to the master cylinder resevoir eventually on a normal functioning brake system.

Answer 6

under normal circumstances - NEVER! The brake fluid system is closed, i.e. nothing else gets in or out under normal operation.
however, if a repair has been done that causes fluid to escape (changing out master cylinders, etc) the mechanic should've bled the system before he put it all back together and let you drive it.

Answer 7

Bleed the brakes lower back. make particular to totally press the brake pedal down and make particular to close the bleeder screw in the previous permitting the brake pedal to return up lower back. shop on with Amber's answer. She especially lots hit the nail on the pinnacle with that one. reliable interest Amber!
