Brake Bleeding Questions Options

[kenshapiro2002]

OK...so I had to tear the left front strut out for replacement, and drained out the brake lines on that side. After I get the new strut in, I'm gonna take it to a local Porsche wrench for a front end alignment and to have him check out my work in securing the struts, ball joints, tie rod ends, etc. I'm sure I did a "bang up" job, but figure I'll let an expert check out my work for any uck fups. When I bleed the line on the front left side because of my work, do I need to do all four corners (hey...haven't bled brakes in 30 years)?

I have "M" calipers off of a 911 up front. Any tricks or special "need to knows" about bleeding these things? Is it easier to buy out of the Mighty Vac thingamajigees?

I would recommend a pressure bleeder instead of a vacuum bleeder as they are worth their weight in gold when doing brake bleeding. In the future, try covering the opening of the brake reserviour with some plastic baggy and screwing the cap back on and fluid will barely leak out if a line is opened.

Another key to keeping fluid in the reservoir and MC is to keep the pedal depressed with a stick. This blocks out the fluid in the reservoir and keeps all the fluid from leaking out.

You might be able to get away without bleeding the entire system but it wouldn't be a bad idea to bleed all 4.

I usually use the pump-up pressure method.

Damn...what a great idea!

Why pressure vs. vacuum? Either way, not something I'll be doing often. Any answer to my question about if I need to do all four corners?

You mean another human being? I'll probably be doing this alone.

Ken, get a pressure bleeder. they cost ~$50, and you can get them from the usual suspects, and sometimes even a FLAPS. Way better then the mighty-vac. Added bonus is that they keep the reservour filled, so you don't need to worry about introducing air into the system.

If the brakes have not been bled in a while, I'd do all 4 corners. If you are using a pressure bleeder you will likely take more time setting everyhting up then actually doing the work.

if ya got the car off the ground,why wouldnt you do all of them,I would stuff new pads in as well if over half worn,front and back and check venting clearance and check wheel bearing,and brake lines,and torque caliper bolts, but thats just me.I dont skimp on anything when it come to stopping..........so YES do it all...jmo

[kenshapiro2002]

Will any of them fit the 914's reservoir for sure? Also, when you're finished, don't you wind up with too much in the reservoir? Just suction some out with a turkey baster? (IMG:style_emoticons/default/confused24.gif)

(IMG:style_emoticons/default/agree.gif) to bleed all 4 corners. Old brake fluid will absorb water and rust out the brake system from the inside. Factory (well, maybe VW Passat) maintenance says flush system every 2 yrs. I have a blog entry showing the Motive hooked up to my car.
Edit: ... or easier if I just paste the pic here

If the fluid is fresh, you can only bleed the one corner. Not a problem, do it all the time.

These guys seem to like making others guys do more than what is needed and more they would do themselves.

Watch me get flamed for this....

[kenshapiro2002]

Yeah, but it works when they do it to me...jewish guilt (IMG:style_emoticons/default/av-943.gif)

[kenshapiro2002]

Yeah...didn't say "the" brakes hadn't been bled in 30 years...said "I" hadn't bled any brakes in 30 years...outta practice. I thought Id read something somewhere here about these brakes being tricky in some way to bleed...guess not.

I was just in the barber shop and some guy was complaining about how is wife was charged $70 to bleed the brakes in her car. This guy says, "I've never bled my brakes, I just add more." He was talking kinda loud and I didn't want to get into it with him. Just let him rant.

[kenshapiro2002]

Of course...if he's leaking enough, it's always fresh! Kind like the British sports cars of the sixties. Never needed to change oil, just keep it topped up.

BTW...know why there are no British computers? Couldn't figure out how to get them to leak oil.

I'm sure all those fancy bleeders are super nice, both times i've done my car I just used this

Worked like a champ. Flame on.

[kenshapiro2002]

Don't see any way for suction...how's it work with one man?

Just hook it to the bleeder and pump the brakes slow. It's like the old guys using glass jars. The loooong hose method works well to, same concept, I just like knowing fresh fluid is going to all 4 corners.

Like they say in the classic`s ,there is no free lunch.In order to get the best results it must recieve constant maintanance ...that all im say`n ,nothing wrong with check`n to make sure its all up to par...need a flame thrower smiley (IMG:style_emoticons/default/poke.gif)

if ya cant find the time and money to do it right the first time where ya gonna find the time and money to do it again...again JMO

I would recommend a pressure bleeder instead of

+1 get a motive power bleeder pro kit with a euro adapter, adapter 0100. If you need a link i'd be happy to provide one as they are an affiliate with a car club I run (IMG:style_emoticons/default/wink.gif)

I just did the brakes on my 914 yesterday as I had a master cylinder failure and used it, uses the SAME adapter that it takes on my 944, works like a charm. It maintains constant pressure and took me probably less than 30 minutes to bleed the whole system.
