2010 Scion xD Parts Questions & Experts Answers

• Q: How to remove and replace the brake master cylinder on 2010 Scion xD?

  A: Begin the brake master cylinder replacement by opening a brake pedal multiple times to drain the vacuum from the booster before draining the fluid while washing off any paint-affected fluid residue. The next step involves unscrewing the cowl top ventilator louver center together with the battery tray and battery carrier and battery removal. Detach the tube of the clutch reservoir by moving the clip and pulling it out. Proceed by separating the brake master cylinder sub-assembly through connector removal of the brake fluid level warning switch followed by use of a union nut wrench to detach brake tubes then uninstall the two nuts. The operator should meticulously handle the master cylinder to prevent impacts while avoiding reuse of dropped master cylinders. The sub-assembly needs to stay horizontal or pointed downward while installation and removal to stop piston loss. The master cylinder piston must remain free from foreign contamination. In case of contamination you should wipe it with a cloth before coating its circumference equally with lithium soap-based glycol grease while excluding other fluids and greases.
