So I'm in the middle of a long clutch and hydraulics replacement job. Installing the new master cylinder, I broke off the little triangular tab. I've ordered a new master.
I'm a dummy and can't remember the angle on the original one.
The master has a rubber hose up to the reservoir, sticking out of the master body, seen here next to the rubber grommet:
What's the correct angle for that hose to be in order to insert the master into the firewall hole (assume 12:00 or zero degrees is directly up, facing the firewall from the front of the car), and what's the correct angle for it to be after rotating the master into position, i.e. how much is it supposed to rotate, and which direction?
I would look under the dash where the MC fits through. You should see which way the ears on the MC need to be. Just remember to mirror image when on the engine side.
The thread is like a pickle jar top. Not like a fine Vernier caliper.
It's about a 1/4 turn to tight and you'll feel it pop into the locked position.
Do your self a favor and put a small C clamp (just finger tight) on the flats of the master cylinder to help you get a grip on the little sucker. You need to be sure it's locked all the way in and it's tough to get a good grip on it. You're using your left hand all the way out and twisting to the right - not the best for leverage.
Well, I know that Dorman sometimes doesn't have the best rep for parts, but I can report that the Dorman master cylinder body is actually metal, and not cheap plastic composite like the OEM and LUK master cylinders are.
