I planned to bleed the brakes on my '49 GMC 3/4 tom tomorrow. Today I went under the truck to put some penetrating oil on the bleeder screws and was surprised to discover that the bleeder screws looked like hex head bolts with a hole in the center. I had expected to find bleeder screws with a nipple like end that I could put a bleeder hose on. How do you bleed with these screws? Surely you don't just crack the bleeders and and let the brake fluid squirt all over the bottom of the truck. Mike M '27 Chevy '41 John Deere B '49 GMC FC-150
They're wierd all right , I just toss 'em out and replace with new ones from NAPA or the scrap yard . BTW : penetrating oil on them will contaminate your brake fluid , causing the rubber parts to die and leak brake fluid... -Nate
Nate - Thanks for getting back to me on this post. I was beginning to think I was the only person who had encountered the odd ball bleeders. Thanks also for the heads-up on the problems caused by penetrating oil. Mike M '27 Chevy '41 John Deere B '49 GMC FC-150
