Brake pedal problem
Did rhe tundra upgrade a couple of months ago with no problems. Within the last week this has happened 3 times. When I go to brake, the pedal is rock hard and I have to push real hard to stop. Brake fluid is full. What else can I check to try and figure this out?? Thanks in advance.

is hard from the start of pushing the pedal like you just pumped it thirty times or is it soft for the first quarter of down travel then the rest is very firm because thats the way mine is and it is alot firmer then any other brake pedal ive used.

Here's an idea to try and locate the problem. Remember to keep your reservoir topped up the whole time so you don't get air in the system
Pull all 4 brake lines out of the calipers and put them into yoghurt containers to catch the fluid. Press the brakes. There should be almost no resistance. If there is, the problem is likely in the master cylinder.
Hook up all but one and press the brakes. Do this for all 4 corners. If it's soft for 3 corners but some resistance when one of the lines isn't connected, it might be a problem in the line to that caliper. Check for a crushed or possibly plugged hard line
If it's soft for all 4, the problem could be in a caliper or booster.
I'm too tired to keep thinking right now, but it sounds to me like either something is binding or plugged in your master cylinder or one/more of your hard lines are crushed somewhere and letting very little fluid through

PROBLEM CONTINUES...........Saturday one of the rear wheel cylinders let go and soaked the rear pads. Wheel cylinder replaced and pads. I also replaced the vacuum line to the master cylinder. My problem is that THE BRAKE PEDAL IS ROCK HARD. It doesn't look like I can replace the check valve and might have to replace the brake booster???? I really don't have the $600 bucks for that. ANY OTHER THOUGHT WOULD BE GREATLY APPRECIATED. Thanks.........
