Hose Assy Front Brake Left Driver Side for Tesla Model Y
1188721-00-B: Core Guarantee for Safe Braking
As a key component of the Tesla Model Y's braking system, this
front left brake hose assembly (1188721-00-B) is specifically
designed for 2020-2022 models, making it the first choice for
OEM-level replacement with precise fit and reliable performance.
Its core advantage lies in being made of high-strength composite
materials: the inner high-pressure resistant rubber ensures smooth
transmission of brake fluid, the outer synthetic fiber braided
layer enhances tensile resistance, and the surface wear-resistant
coating effectively resists gravel impacts and road salt erosion.
This structure allows the hose to remain stable in extreme
temperatures ranging from -40°C to 120°C. It will not rust and
block like metal pipes, nor will it crack due to aging like
ordinary rubber pipes, with a service life of more than 60,000
kilometers.
During braking, it plays a crucial role in transmitting master
cylinder pressure to the front left brake caliper. The precise pipe
diameter design and seamless one-piece molding process ensure that
the pressure loss is controlled within 0.5%, enabling immediate
response when the brake pedal is pressed and eliminating the "soft
pedal" phenomenon. At the same time, the hose can bend flexibly
during suspension movement without wrinkling, always maintaining
unobstructed flow - which is crucial for the front wheel braking
system that frequently turns.
No additional modifications are required for installation. It
directly matches the original fixed points, and with the included
sealing washers, professional technicians can complete the
replacement in 30 minutes. All products have undergone a 72-hour
pressure test (2500PSI without leakage) and come with a 12-month
warranty.
Choosing 1188721-00-B is not just replacing a part, but also
building a solid defense for the braking safety of the Model Y,
making every deceleration precise and controllable.
