Ok guys,
I have a strange problem for some time. For several months in the morning or after 5-6hrs rest, brake pedal on 2015 Sienna is super soft, and barely stops getting out of garage on 7% grade. 2-3 braking attempts and things go back to normal. Thought first worn pads, as I sucked out any life out of them, installed Pagid pads, Element3 rotors, but same thing. I kept forgetting but last two weeks I was driving car more as I was upgrading suspension on BMW. So yesterday I decided to check pads as I was switching from winter to summer tires. In addition to discovering leaking strut, everything on calipers looked normal. All springs, retainers etc are there. No loss of fluid. Anyway, I decided to replace all hardware on pads, but nothing. Today same thing.
At this point I am suspecting that it is master cylinder. But, what is confusing me is that brakes are normal after few braking attempts. Actually, these Pagid pads are super responsive, nothing like mediocre OE ones.
Anyone? Trav? Critic?
