02 maxima. Been lookin online about how to replace the master cylinder and came across some cylinders being step bore cylinders. I could not find any good information on google about this, but what is the difference between a step bore master cylinder and a conventional one? And which one does the maxima have?

Also just bought a brand new master cylinder and it has that plastic piece on the end of it (see pic), do I need to remove this or does it stay on? Also are there any parts I will need to transfer from original master to A1 cardone master?

 

You don't need instructions. Take off the brakes lines, unbolt the cylinder, bolt new one in, "bench" bleed it, connect lines, bleed brakes.

 

There's not much to the master itself. Read up on bleeding the brakes properly if you're not 100% familiar with doing a four wheel bleed. It's not hard but it needs to be done right.

One tip. The hard metal lines can be a b!tch to get started without crossing threads. Don't force them. I like to slide the part in place then start the lines while the part is still moveable. Once the lines are started, install and torque the mounting nuts. After the part is secured go back and torque the lines.

I'm not sure about the plastic piece. Just pull the old one and see what it looks like. When I work on something I'm not familiar with I always pay close attention to how it comes apart. The old part will usually have clues as well. Wear marks, circles where the fasteners were etc....

Also. Get a box of disposable exam gloves. Between the removal, install and bleeding you're going to get brake fluid all over your hands. It wont kill you but it's nasty and messy.

 

This. I hate brake fluid with a passion. Keep that sh^t away from your paint or else it'll eat right through it.

 

Yeah that plastic piece stayed on, and it took me 10 min. to get 1 of the brake lines back on, but other than that, easy.

 

Good deal. Those type of rigid lines can be a hassle but it's way better to take your time than to cross the threads.
