X‑Class 60V: My brakes are squealing

Spongy lever: inspect for leaks, top up fluid, then bleed with mineral oil; pump the lever to settle micro‑bubbles and restore a firm feel.

<h3 id="firm-it-up">Firming up the brakes</h3><p><span style=" text-decoration: none;" id="isPasted"><span style="font-size: 14px;">Hydraulic bicycle brakes feel spongy when air gets trapped in the brake lines, since air compresses much more easily than brake fluid. Other causes include contaminated or old brake fluid that has absorbed moisture, worn seals that allow air to enter the system, or insufficient fluid in the reservoir. These steps should help you get your brakes working like new.</span>&#xA0;</span></p><ol><li>Check for leaks at caliper and lever.</li><li>Top up fluid if low and bleed with mineral oil (Shimano&#x2011;spec).</li><li>After bleeding, squeeze lever several times to settle bubbles, then recheck.</li></ol><h3 id="related">Related</h3><ul><li><a href="https://arielrider.gorgias.help/en-US/service-intervals-xclass60v">Service intervals.</a></li><li><a href="https://arielrider.gorgias.help/en-US/brake-squeal-xclass60v">Brake squeal.</a></li><li><a href="https://arielrider.gorgias.help/en-US/replace-brake-pads-xclass60v">When to replace pads.</a></li><li><a href="https://arielrider.gorgias.help/en-US/pressure-wash-ok-xclass60v">Pressure wash OK?</a></li><li><a href="https://arielrider.gorgias.help/en-US/tire-pressure-xclass60v">Tire pressure.</a></li><li><a href>Contact us.</a></li></ul>
