Restore the seal between the brake booster housing and plunger with this URO power brake booster seal, part number 4836664S. It is an OE-style replacement for Saab 9-3 and Saab 9-5 applications where a hardened or cracked seal can create vacuum leakage and reduce braking performance.

• OE-style seal profile and durometer for proper compression at the booster-to-plunger interface
• Heat-resistant seal material for repeated plunger cycling in the brake booster
• Direct replacement for worn booster seals that no longer hold vacuum
• Fits 1999-2009 Saab 9-5, N/A
• Fits 1999-2002 Saab 9-3, N/A

Application Details

This URO 4836664S brake booster seal is built for vehicles that need a precise sealing surface to maintain vacuum integrity in the brake assist system. It is a practical choice for Saab 9-5 and Saab 9-3 owners addressing brake pedal feel changes caused by seal wear, cracking, or hardening. This part cross-references URO-013800 for the same application.

Common Problems It Can Address

• Vacuum leakage at the brake booster seal
• Brake pedal feel changes caused by seal deterioration
• Loss of proper compression between booster housing and plunger
• Cracking or hardening of the original seal material
• Reduced brake assist performance from a compromised seal

Installation Notes

Inspect the booster sealing surface and plunger area before installation. Clean away old residue so the new seal seats evenly, and follow the vehicle service procedure for brake booster service on Saab 9-3 and Saab 9-5 models. Verify vacuum integrity after installation and confirm normal brake pedal operation.

Quality Assurance

URO backs this part with a 24 Month Unlimited Mileage Warranty. The seal material is selected to resist engine heat and repeated cycling, supporting long-term service in the brake booster assembly.
