'74 914, all stock, near all original, 22k
As we all know getting the brake hose disconnected from the hard line can be a pistol on older cars, Heat always works, while doing the front end of the 914 (shocks and bushings) I am replacing the hoses - of course\ I needed to heat and started to torch (IMG:style_emoticons/default/blowtorch.gif) this connector when BANG! Turns out there was a very tight fit between the hose and connector, enough to hold pressure to an explosion point. Who Knew!?! Fortunately, I was wearing goggles. No, there were no blocks within the hose, this was not from what was IN the hose but between the hose and the connector.  |

you should probably also check the adjustment of the actuating rod on the master. there should be clearance. there is a spec in the book, don't recall what it is.
If the clearance isn't there then the master can be slightly depressed even when your foot is not on the brake pedal. this prevents pressure from bleeding off the system after every brake application as some of the heat of braking is transferrerred to the fluid. this can cause a big problem if not corrected before driving. As heat builds, the brakes will not release completely, which builds more heat. It's not good. I have to agree with advice above. If the lines are trash I usually cut them before I go for the torch. |
