2nd Gen Non-Engine/Transmission Flushing brake system

[AggieJustin]

OK, I'm going to put on the GM wheel cylinders this weekend (hopefully). While I was at it, I was planning on flushing the brake fluid as the stuff I have now is looking pretty nasty.



Any tips/hints on things to make the job easier? I usually learn things the hard way, but I want to try it the other way one time.

The uggly stuff floats to the top , so suck out the res. then open the petcocks [if they havent been opened for a while spray some penatrent on them for a day or two before your going to work on it ] and while your working let all four end drain but keep res. full that will clean out the system and keep air out witch is where most crud comes from, if you do'nt let the res. go empty then just close the bleeders and check peddle , more offen than not you not have to do any bleeding becouse you just let the fluid flow and never let any air in , even the new cylinders , once there in just let gravity do the work.

I have a mighty vac and found it was better to go with speedy bleeders that I got from Napa. They have a check valve built in so no air gets into the system. All you do is loosen them and then pump your brakes while keeping the reservoir topped off. When the fluid color changes to clean fluid just tighten then up and you are done. I have read about many problems from compressing the wheel cylinders or calipers and sending the contaminated fluid back thru the anti lock system or proportioning valves.

Where did you find the speed bleaders?, I have been looking for them for an 02.

How I Do It Is Get Somethign To Suck The Fluid Out Of The Res On The Master Cylinder And Fill With New Fluid It Takes A Lot Less Time To Flush That Way. Instead Of Sucking All The Old Fluid Out First Then Pulling New Fluid Through.

I tried NAPA, no idea.



Does anyone know the thread pitch of the brake bleeder screws? A local parts supply can order them if they know the thread pitch size. Nothing listed by make or model.
