Brake pedal long travel when is raining

[Turbo_Boss]

Hey guys,

I have a 2002 1.8T with 62,000kms

It has new brake pads in the 4 corners installed at 61,200kms.

In normal days, the brake pedal travel is normal but as soon is raining the brake pedal travel is more. I will say its almost the double.......... Its look like the brake system knows is a little colder/raining and the brake pedal behave that way

In none of the cases, the brake pedal is spongy. There is no brake oil leaking

Car is breaking OK just the brake pedal travels more until I feel resistance.

I try it breaking very hard and the ABS activate as normal

The brake fluid reservoir is full and the color looks OK

The brake booster vacuum plastic pipe is all new. I replaced a few month ago.

What can be the problem?

THX,

Isaac

Grammar nazi mode, it's: braking, not breaking

It should behave equally in both weather situations. I would try to bleed the brakes, just to be safe (maybe even better with fresh brake fluid).

I do not replace the disc rotors........... I only installed new regular brake pads in all 4 corners. Brand is VIKA PARTS AUTO QUALITY (Czech Republic brand) But maybe they are made in China

I have use this same brake pads brand in my daughter 2.0 Jetta MK4 and they are OK
