Master cylinder replacement (DIY or have a shop do it)

I've had a softer pedal feel on my tundra for awhile(was just hoping that's how Tundra's were). I took it to a shop for a pre-trip inspection and they let me know that I have a leak in my master cylinder. Just looking for advice on whether I should do it myself or have a shop do it.




PS. I would say I have intermediate mechanical knowledge

 

I dont think it's very difficult. Are you losing brake fluid?

 

No, they said it was an internal leak(not really sure how that works but that's what they said)

 

Get a 2nd opinion...

 

An internal leak will show up as a brake pedal that keeps moving closer to the floor if you keep applying pressure with your foot. If your fluid is dark in color you may have a rusty bore in the master cylinder causing the leak. If this is the case your calipers/wheel cylinders may also need replacing.

 

My 2007 got mushy. Replaced my master, and my calipers pads and rotors while I was at it. I just Started doing some minor stuff mechanically a few years ago. Super novice. The biggest pain in the ass is getting the flare nuts into the new master correctly and not cross threading them.

took care of my mushiness. I knew If it didn't, the brake booster was next on the list. But I was Good to go.
