Detailed Description

URO 93035255400 is a rear disc brake caliper spacer kit for the Porsche 911, covering 1978-1989 models. The EPDM rubber and stainless steel shell construction is selected for brake-system durability, while the OE-style profile and durometer help maintain proper piston protection during repeated braking cycles.

This part cross-references URO-013918 for the same application.

What It Helps Address

  • Cracked or hardened brake caliper piston boots
  • Moisture intrusion around sensitive caliper components
  • Debris contamination in the rear brake caliper area
  • Heat-related wear from repeated braking
  • Loss of sealing integrity in aging Porsche 911 rear brake hardware

Installation Notes and Tips

Verify rear brake caliper measurements before installation and compare the old boot or spacer to the new part. Clean the caliper area thoroughly so the sealing surfaces are free of corrosion, brake dust, and debris. Confirm fitment against the 1978-1989 Porsche 911 rear brake application before assembly.

URO backs this part with a 24-month unlimited mileage warranty. The design uses high-quality materials intended to meet the demands of brake heat and everyday service on Porsche 911 rear brake systems.
