A-Premium Brake Master Cylinder with Reservoir and Sensor Compatible with Nissan and Infiniti Vehicles - Pathfinder 1996-2001, QX4 2001, RWD - Replace# 460100W003

Unfortunately I am struggling to find a master cylinder that matches my cars requirements. The reviews here were bad, but I took the risk. The part blows out on the side port as others mentioned and will not hold pressure in the system. I bled the master cylinder first, followed by bleeding each caliper on the brakes prior to testing. As soon as pressure is loaded it blows brake fluid all over everything.

Did a bench bleed with no problem, but when I installed it in my 2000 Nissan Pathfinder Rwd, when I depressed the brake pedal with the engine running, like another reviewer stated it blew out the rubber plug and brake fluid sprayed out of the side hole in a heavy mist. I wiped it all up refilled the reservoir and tried it again and no leaking out of the hole this time, I bled all brake lines took it for a test drive and it is working fine. I believe there is a small piston behind that hole that needed the pressure of the brake booster to seat it and fill with brake fluid.I will update if I have any issues in the future. The Amazon price was a fraction of the cost of my local Advance auto price, delivered next day!

This piece of crap didn't even make it through the mechanics test phase, it blew out a rubber plug to the side of the brake lines and it's not like there was no other piece (Metal) in the kit to plug or even screw in the hole. The OEM one has a metal allen key hex head screw in it for that hole so why would a manufacturer use a rubber plug.

Just trying to bench bleed and it shot fluid out of the weep hole. Do not buy
