bleeder valve open on caliper?

[myfinalcoffinx]

I have in the past, but it seems like more hassle than it's worth, but I'll run it by you guys.

 

In the past, I've opened up the bleeder valve on the caliper when changing my pads as to not push old fluid back into the master, but every time I do that, I need to bleed the system, and it gets kinda old.

 

What do you guys think about not opening the valve and doing it that way?

I've done it w/o opening valve, but even tho a PITA, I would still recommend opening the valve and doing it that way. It may be in the long run you might end up having to bleed them anyway.

 

Rather be safe than sorry

I have done it without opening the valve, but ONLY on systems where the fluid appears to be in very good condition and is not likely to have contaminants that can be pushed back into the system.

 

If your fluid is more than a few years old, you really should flush it anyway.

Always seems when someone is right I have more work to do.

so true. and yes I always open bleeders when compressing pistons.

its not so bad on the subes if you have a good caliper compressor. not just a pair of needle nose pliers.

 

this applies mostly to ABS equiped cars but is just a good practice in general.

er um .. why dont you just remove the cap off the master cylinder before you start pusing the piston back into the caliper. Thats how ive always done it, thats how we were taught in school, and thats how my mechanic does it (yes he still bleeds the system). In winter i refuse to work on the car outside so i bite the bullit if its a brake issue and let him do it.
