Hi All,

I'm new to this forum and I need your guys opinoins on brake system.

I have a mountain bike with full suspension, disc brakes with hydraulic brake system. The bike is about 10 yrs old and I rarely ride it.

The hydrulic fluid leaks, hence cause brake malfunction. I need to bleed the brake line and add fluid every couple weeks. I have been using the oil I bought from Wal-Mart. Someone in the bike shop told me I should have used special bike brake fluid for it, so now the oil caused the brake to leak. Does it make sense to you guys?

Should I replace the hydraulic brake system with classic cable brake system?

I apprciate any inputs.
