The GMC CCKW

has any one done there brakes with a vachume brake bleeding kit as im thinking of buying one to do brakes on my 353 i have tryed the book way but cant get a decent feel as i had before any help would be great i dont have any one to help do thisso need to be able to do on own thx

I use a simple garden bug sprayer available at any home and garden store. I made sure the one I bought had a brass hose between the switch and the nozzle.



I removed the end nozzle and attached a 1 foot length of clear plastic fuel line. I then used an old Master cylinder reservoir cap and placed a brass barb in it.

Attach the hose to the barb. You put some brake fluid in the sprayer and put it under minor pressure. You can go around and bleed the brakes at will. The transparent sprayer indicates the amount of fluid left and the clear hose will give you an idea of how the fluid is moving to the master.

Total cost under $20usd.

I find this a better setup than the vacuum pump hand unit. It is easier to push it than to pull it and I don't have to keep going to refill the master reservoir.
