Confirm your snowmobile's brake assembly
For an MX Z, Summit or Renegade, check the exact year, package and engine in the parts catalog before ordering. These model names cover several configurations. Confirm reference 507032478 for the reservoir and compare the underside seating surface, post position and cover with your existing assembly.
If the snowmobile has a replacement master cylinder or modified controls, identify the fitted brake assembly first. Reservoir capacity, dimensions and screw thread specifications are not provided here.
Brake fluid and service checks
The cover carries a DOT 4 marking and a reminder to clean the cap before removal. Confirm the fluid requirement in your snowmobile's operator guide and service manual before filling the system. Brake fluid is not included.
Follow the exact model's procedure for installing the reservoir, seating the seal, tightening fasteners and bleeding the brake system. Check for fluid leaks and correct brake operation before use. If the master cylinder itself is worn or damaged, plan that repair separately.
