FAQ
Q1: What is the relationship between part numbers LR039593 and LR025602?
A: Part number LR025602 was the original factory designation, which has been officially superseded by the material-upgraded part number LR039593. They share the identical spatial dimensions and fitment profile.
Q2: Can a worn vacuum pump gasket cause an erratic or hard brake pedal?
A: Yes. If the seal fails completely, air can bleed into the vacuum loop, causing a pressure drop that starves the brake booster. This results in a heavy, stiff brake pedal and longer stopping distances.
Q3: Do I need to apply liquid gasket sealer or RTV along with this rubber ring?
A: No. This gasket is precision-molded to seal dry out of the box. Applying liquid sealants can alter its seated height and interfere with the dual-lip design, potentially causing a new leak.
