Brake master cylinder went out

So yesterday as I was driving my 2000 Tundra Sr5 4x4 to Borrego Springs from San Diego I noticed my brake light come on. I thought it might be a sensor going bad or something. I was wrong when I got to Borrego springs I had really no pedal left. No brake fluid left in the reservoir. The brake master cylinder is leaking and brake fluid is running down the booster. I was wondering if anyone have replaced them before and knows the brake line but size so I can get some flared wrench’s to fix it when the part comes in. I’m just glad my brakes didn’t give out going though all those curves.

 

That's one hell-of-a-place to have a brake issue. Good luck with your repair and keep us posted with your results.

 

I bought a 12mm and 10mm Combo Wrench for the wheels brakes bleeders. Ended up getting an 8mm for my new (smaller aftermarket) bleeders valves. I’ll check for you later, but it might make sense to buy an 8,10,12mm just so you have them for later brake work. I’m assuming you need to bleed all your lines/wheels/prop valve anyway. Flare wrenches are nice.

 

Thank you @prof

thank you. I appreciate it. I’ll buy a set.

 

You only need the flare wrenches for removing/installing the lines. Use a 6 point socket on the bleeders -- you'll get a better bite. But if you can afford it, it's never a bad idea to have a full set. They come in handy for working on A/C, power steering and transmission lines. When you don't have the full set, you tend to try to make due with an open end wrench... which can lead to a rounded fastener.
