Master brake

[Hadyn]

Does this require replacing master brake cylinder or brake booster.
Or is this just a gasket.
Any help would be great.

That's your master cylinder leaking. I had to replace mine a few years back,
and the job's straightforward. Not hard at all. You'll need to swap your
plastic tank to the new master cylinder, but again no problem.
Use a flare wrench to prevent rounding of the fittings, and bench
bleed the new cylinder to reduce the brake bleeding procedure.

Hi Hadyn, 99 v8, nice vehicle. You want to be sure you do not get any air bubbles in the ABS system. You will need to bench bleed the new master brake cylinder and be sure the tubing (that is where you disconnected the master brake cylinder) full of brake fluid. You can search this forum for and see it is not so easy to bleed the air out of the ABS system.

Thanks everyone. So I'm very new to all this. Lol it the silver metal part that needs replacing not the black round part at the back. I will research the bench bleeding.

yes the hydraulic master cylinder needs replacing
the brake booster (black metal round thing) only holds vacuum (air) no fluid is present
that is one nasty brake fluid leak! get that fixed, brake fluid is flammable!!

Unless the black part is full of brake fluid!

++ On that!
If you let any air into the ABS hydraulic control, simple bleeding won't remove it, and you will be in trouble (as in the pedal going all the way to the floor and the vehicle not stopping). Although it's not that difficult to correct if you have a decent scanner (like Forscan), at this point most people end up towing the vehicle to a well-equipped garage and pay the big bucks for a rather simple (for the mechanic) procedure. To avoid this, make every effort not to let air into the system. As advised above, make sure that the lines that you disconnect from the master cylinder remain full, and the new master cylinder is filled up and free of air bubbles before you install it. The process of properly removing air from its chambers before installation is called "bench bleeding". All it takes is a couple plastic fittings and little tubes that most auto parts stores will have in stock. There is probably a dozen YouTube videos showing how exactly to do this. Good Luck!

Thanks for all the advice.
