I asked a shop to replace my brake fluid when I brought my 1994 Celica in for alignment. Upon picking it up they said that they could not do the brake fluid flush because they didn’t want to risk breaking the bleeder screws, which would have required me to get new calipers and drums. It’s the secon…

At RockAuto.com , calipers are less than $50 each, and rear wheel cylinders are less than $10 each. You will obviously pay a shop considerably more for the parts, and also pay for a few hours of labor, but you might want to consider just having the parts replaced.

The other important portion of changing the fluid is getting it out of the calipers as well, in order to keep their internals free o…

As a lesson for those folks who don’t do this very often: What tricks have you pros used to get the bleeder screws loose? I’ve used repeated application of a rust penetrant, such a PB Blaster - along with some tapping on the screw head itself. I also use a 6 sided socket, so I can gradually add p…

I certainly don’t have any techniques or tools that a professional shop wouldn’t have already tried but that Phoenix Systems thing is interesting. Interesting also to consider bleeding through the banjo bolts but there must be a good reason the shop doesn’t do it that way as an alternate method. Ma…
