SEAL - UCUP, BRAKE FLUID (Toyota TY00591-20040-81)

A damaged brake fluid seal can lead to fluid leaks and reduced braking performance. The seal type known as a UCup seal is designed to contain fluid under pressure within a cylinder. During normal operation, the seal's lip maintains contact with the moving surface to prevent leakage. A worn seal may allow fluid to bypass, resulting in spongy pedal feel or loss of brake function. This aftermarket replacement part references Toyota as the OE maker and carries the cross-reference number TY00591-20040-81. The item ships at approximately 0.01 pounds.
