Will Gasket Sealer Fix Spongy Brake Pedals?

This method is useful for when you notice soft brake pedals, but no leaks within your brake system.

Or you may have just bled your brakes recently / installed a new brake caliper, but still notice spongy brake pedals.

If this is the case for you, there is a solution which may work as a complete repair.

5 months ago I used gasket sealer to fix a leaky brake caliper issue. As the brand new refurbished caliper would constantly leak air bubbles as I bled the brakes; even with the bleeder screw closed!

Now I'm testing how well things have turned out since I've used gasket sealer to pinch off the leaky bleeder screw.

*The Results*

Since then, the brake caliper has done a good job of braking. After 5 months there has been no signs of spongy brake pedal, and the stopping power of the brakes are still firm and solid.

However, I ran into the same problem again when I changed out another caliper on the other side today.

The 2nd newly refurbished brake caliper started to leak air bubbles again.

So I used the same method as before 5 months ago and pinched off the bleeder screw once again.

*Caution - This is a Last Resort method.* If you've already tried to repair your leaky brake issue and nothing else has worked, then this option may work for you.
