Does anyone know the proper procedure in changing the brake pads without unbolting the caliper?

Hope this helps.

Thats exactly the procedure for the 350 at least, easiest brake job I've ever done. A C-clamp, a needle nose and a standard plier, a rag, and some brakleen is all you need.

Not sure about the 250, might be different.

Good diy, thank you.

Am I required to bleed/flush the brake fluid?

If you don't open the fluid cap, then no. It's a closed loop system. If the fluid is more than 2 years old, then "I" would get new fluid. Not mandatory, but brake fluid hygroscopic over time.

First time changing brakes on my own.

What is the reason to open the fluid cap? How do we know it's a closed loop system?

My0gr81

Brake system relies on closed loop where hydraulic fluid gets compressed to push a piston that then pushes the pads against the rotors. The c-clamp is used to push the piston back, so it will push the fluid backwards through the system and back into the master cylinders that contains the fluid. Some mechanics will open the cap of the master cylinder to make it easier to push the caliper's piston back. If you do, then air gets in the system and you need to bleed it.

Guess we'll see what happens when i change em out
