Do you need a vacuum line to brake booster on a non disc brake car?

If you have a booster you need a vacuum line to perform effectively, disc or drum.


Do the you band and H zones become narrower during contraction?

Yes the H band shortens. During contraction the length of the sarcomere or from z line to z line must decrease in length. Thus the I band which is bisected by the z line must shorten as well as the H band, even though the H band is bisected by the A band it must shorten to allow fior this decrease in length. The A band does not shorten because it is composed of the entire length of myosin whose length never decreases during contraction.

Sarcomere think filaments are linked laterally by proteins of the?

sarcomere thin filaments are linked laterally by proteins of the Z-disc, such as α-actinin. These proteins help stabilize the alignment of actin filaments within the sarcomere and contribute to muscle contraction.
