Tips From the Week's Brake and Tire Projects

Previous owners had replaced the rear brake calipers on the E450 we bought in late 2008. I found one bleeder screw badly stuck, had to bang on the six-point 3/8" box wrench but did get it loose. Other bleeder rounded off even using a new six-point socket. Was able to remove using Channel Lock pliers but couldn't get to the bleeder with those before I took the caliper off. So:

Tip Number One: Put a little NeverSeez on the Bleeder Threads! I power wire brushed the rear bleeders (had a spare from an old caliper) and applied the compound. Today I took the bleeders out of the new calipers and applied compound. I can only hope they can be loosened in the future.

Tip Number Two: Air-Through Tire Valve Caps. If you got a set of custom valves from Chuck (Tire-Man) recently they came with these caps. They keep dirt out, protect and don't depress the valve stem, and make checking/airing as easy as pushing your gauge or air chuck on. They're known as V2B, Gator, and Crocodile but I found them at NAPA yesterday as NAPA 90-319 or NTH 90319 (for Napa Tire Hardware). Four for about $6 on one of their spin-around racks. I've seen them for less but there's either shipping or you have to buy dozens. They're simply great.

  • I use plumbers tape, that white Teflon no-stick ultra-thin rubber-band-like tape, used for the bleeder screw threads primarily so the air does not get past the threads so badly when using my vacuum bleeder hand pump. I've hoped the tape will also prevent seizing, but I never had a vehicle long enough to know for certain that the plumbers tape does any good in that regard.

    I don't disagree. I think the spare I had was some how a new one and I didn't brush it. Nor the two new ones in front.

    How "standard" are these things? Something I've never bought. At least on the chain store auto parts, "Bleeder Screw" is not among "Replacement Parts."


    Well worth the money I think. Google up "stainless steel brake bleeder screws".

    Last couple brake jobs on pick up and wives car I've started using 3m silicon paste on pivot points, like the bolt that holds caliper on and has rubber bush at end. Anti seize was eating getting into rubber bushings I think. Verdict still out if better or lasts longer. IMO

  • Better to replace bleeders with new ones than to wire brush them because that removes the coating that's left and promotes worse rust.
    Never - seize works great.
    Good Luck, Mike
