  1. 1987 Quad Spider brake issues

    Spider - 105 & 115 Series (1966-1994)
    Hi.. I pulled this low mile spider out of storage to get back to excellent running shape. The front calipers were sticking, so had them rebuilt. When I reinstalled them, the brakes felt pretty good, but not amazing. (I have an 86 Quad as well to compare). I noticed a fluid drop, and looked...
  2. 750 Master Cylinder Fittings

    Giulietta & Giulia (1954-65)
    New Master Cylinder just arrived from Centerline for my 1957 Giulietta Spider Veloce. Does anyone know what size threads are used for the fittings? I believe it is a Girling, but not sure. Old M/C was of unknown type and brake lines do not fit. See picture attached.

  6. Leaky brake reservoir

    Spider - 105 & 115 Series (1966-1994)
    Hey Gang, I'm regularly having to top off my brake fluid reservoir. I believe the fluid is seeping out of the bottom of the reservoir. Of the two rubber grommets connecting the reservoir to the master cylinder, the one closest to the firewall looks wet. Advice on continuing my investigation...
  7. Brake MC Stumper

    Giulietta & Giulia (1954-65)
    I am stumped. I have a 65 Giulia 1600 Spider with Disc Brakes. I was pulling the car out of storage this summer and the brake pedal goes to the floor - all slave cylinders were rebuilt within the last 5 years w/all new rubber hoses. No fluid on the ground or on any wheel. Master Cylinder...
