You guys may think I'm nuts, but I've been doing this for about a year and cant believe how well it worked. Because I haven't wanted to deal with a brake bleed due my assistant always being busy, I started using a syringe to suck brake fluid from the reservoir. Suck it dry to where their is just a little fluid left to keep air from getting into the system. Then wipe out any remaining residue with clean cloth and refill with fresh fluid. drive a little while, then rinse and repeat. Over time, my fluid has become crystal clear. I'm not saying this is a panacea for a proper brake bleed, but it will definitely give a head start when it comes time for a proper bleed. and its super simple.

 

Yeah, I did that before I did my brake job just to get some ok fluid in the system. Gave me enough pedal to make the car movable.

I invested in a pneumatic bleeder can and managed to get a good bleed solo.

 

I have a long bar that I squeeze between the seat and the pedal. I ususlly gravity bleed first if doing a caliper or something towards the end of the line. The pedal doesn't need to go to the floor and I've never had issues getting air out the lines. As low tech as it gets but it works for everything I've done. Granted I also work on an airport where most the equipment is about as high tech as the bar.

 

I don't trust the self bleeders for this type of master cyl. the screw on types work great tho. just to be clear (pun intended) I'm simply exchanging pretty good fluid, with brand new fluid. Diluting may be a better word. Over time, it seems most of the old has been diluted away.

 

If the fluid in the reservoir stays clean in an otherwise dirty system then that pretty much proves fluid doesn't move around the system and it's not helping, Got to flush it because the worst stuff is probably down in the calipers.

I have speed bleeders at every corner. Cap it with a hose to keep a head of fluid on the valve and you got a one-man bleeding system.

 

The brown/orange sludge managed to repopulate in my reservoir after a couple weeks when I exchanged the fluid so there is a bit of movement there, but I agree there is no replacement for a flush. I still had chunky root beer stuff coming out of the back calipers afterwards so it doesn't get real far.

 

Honestly I think LiquidBlue is simply bored. Had a lot of fun bringing the car out of storage and getting it back on the road. Now that is winding down and there's a car builder inside of him that wants to come out and play. Maybe needs another car to build....

 

Ha ha QT! Your a funny guy, lol. I was killing time the other day, and did it again, and thought, hey, I will share this with the boys over at 3rd Gen. And ya, it started brownish, and it was very clear the other day, but not perfectly clear, so did it again. When I first started this, you could see swirls of what was probably rust dissolved or something. Now its more like almost clear, but not quite. So, pretty sure the fluid is circulating to some degree. The gunk was probably lighter than the fluid, so it floats back to the MC. But now, no more gunk, could be trapped in the calipers, who knows. The car will eventually be getting a new diff from a 90 T/A and then front and rear 1LE setup will be installed, along with peppier rear end gears, so still have plenty of work ahead! And that is when the real real flush will occur!!

 

Aha, so you are willing to modify that car.... Interesting development.

I hope to follow a build thread for years to come! People that are hands on have the most fun!

I've seen that Abubaca got pulled over to the dark side too.

 

Ha ha, only with correct, factory parts my friend!

 

This is pretty much the same process they use for the C5/C6 Vettes to keep the clutch fluid clean. But yea, its not a replacement for bleeding.

 

It's like doing a new master, you bench bleed it and install it full, but when ever you go to flush and bleed the system, like stated earlier the fluid by the calipers is quite bad still. Its actually surprising how much it will take to get it flushed to see clean fluid. This last time I used some parts store Prestone DOT3 to flush the system out and as a sacrificial fluid, due to the low cost, I didn't care how much I used, over flushed at each caliper to ensure the fluid was super clean. Then after that rebled the system and displaced it with the good Wilwood fluid I wanted to run.
