I have my 2nd 74 2.0 and having issue with brakes. Rebuilt all 4 Calipers due to a stuck Front Caliper. Had a pretty firm pedal prior to rebuild, but could have been the stuck caliper? Anyway bleed everything yesterday per all threads I read and got a firm pedal. But then after it sat for awhile, the pedal would go almost all the way down on the first push but would then pump up on successive braking. After sitting overnight, now I have nothing today. No leaks and fluid level still where it was yesterday. Bleed about a gallon through with a power bleeder.
I’m thinking Master Cylinder now and wanted to get feedback on thoughts and what brand of Master to buy? It’s still the original 17mm Cylinder which I want to stay with. |

How many times have you gone through the bleed/soft/pump up cycle? It can take more than one time; some people like to go through the whole process two or three times, including driving the car in between. (Not with a pedal that goes to the floor obviously!)
That said, it could be the master cylinder. Or if you got air into the MC, that can be a pain to bleed. Also if air gets into the proportioning valve on the firewall behind the driver's seat, it can be a bit tough to get out. --DD |
