    Brake pads and Gear oil

    I am looking at getting some new brake pads and I was wondering what you guys Recommend front, rear, and also thought about doing e-brake boots.

    I am also looking at changing the fluid in the differential, transfer case and transmission I am going to use redline and I want to make sure I have this correct:

    3QT MT-85 for transmission
    1QT shockproof heavy for transfer
    2QT 75W90 for differential

    now what's the difference between GL-4 and GL-5 for that because all I am finding is GL-5 and I found synthetic and synthetic NS (non-slip).

    I know you need a specific GL-something for the transmission (think GL-4 but not sure). Most people that use Redline is the trans use a mix of MT-90 and MTL I think.

    As far as pads, what will you be using the car for, how much are you looking to spend, and what year is your car?

    Do not use GL-5, GL-5 gear oil will eat your synchronizers in the transmission. MT-85 is GL-4.

    Since it's your DD and you're not going to track it just buy some ceramics or whatever from Autozone or Advance.

    Pros: Better protection for the gears
    Cons: Smells even worse than normal gear oil

    Here are my thoughts.

    I've tried:
    Syncromesh
    Royal purple
    Redline mtl
    Diaqueen

    Syncromesh shifted the best of course. I stripped all of the teeth off my 2nd gear outer syncro while drag racing with it. Could have just been lucky though.

    No problems at all with the royal purple syncromax, but it is super thin, so I was too worried to keep running it. I tried their 90 weight and it was almost unshiftable when cold.

    Redline was very good cold or hot.
    I heard diaqueen would be less notchy, but it is not.

    I'm going back to mtl. It is more available and feels slightly better imo.

    Heavyweight shockproof is great, but leaks from the breather on the transfercase. I changed to redline 75w 90 and no more leaks. Maybe shockproof is better, but not if it leaks on the ground.

    I know there are designs out there to combat this, but just changing gear oil fixed it for me. Not worth the trouble.

    I used MTL but would get MT-85 now that it is readily available. I have 75W90 in both T case and Diff with no issues.
