 | This is the new 80mm brake caliper. It must be modified by removing the cast "boss" left of center above the piston. |
| Some careful use of the grinding wheel removes the boss level with the rest of the casting. |  |
 | On this particular vehicle, there was a rectangular "flashing" on the passenger side hub that prevented the caliper from seating. Once it was removed with a die grinder, the caliper slipped right on. |
 | The 80mm caliper has a different hose fitting arrangement than the original caliper. It uses a "banjo" bolt instead of the inverted flare of the original. The necessary hoses are readily availabe, but must be bent to clear the ball joints and CV joint boots. |  |
| The hose end is steel and has been placed into a vise with padded jaws to prevent scarring. Bend that hose very carefully. |  |
 | Here is the almost completed installation. Almost because the hose is still too close to the CV joint boot. It was removed and bent slightly more for clearance. |
