DIY: How To Replace/Rebuild A Brake Master Cylinder
The brake master cylinder, indeed the whole brake system, is probably the most important part of your vehicle. It is a fairly easy job to replace or rebuild and something a beginner can easily do.
What you will need:
Before You Start:
- Open end or box wrenches
- Line wrenches
- Small pry bar
- Snap ring pliers
- New or Rebuilt master cylinder or...
- Master cylinder rebuild kit
- Fender covers
- Brake cleaner
- Fresh brake fluid
- Brake lube
- Safety glasses
- Shop towels
- Pail of clean water
- Latex Gloves (Optional)
- Follow these instructions carefully. Read and be sure you understand them before you begin.
- Gather together all of your tools and supplies before you begin.
- Allow plenty of time to do the job so you don't have to hurry.
- Remember that these are general instructions. For more detailed instructions pertaining to your specific vehicle, consult an appropriate repair manual.
- Beware of hot objects, sharp instruments and hazardous materials.
- Don't substitute tools unless you're sure you won't compromise either your safety or the performance of your vehicle.
- Never work on a vehicle that is only supported by a jack. Use jack stands to support the vehicle while you work. Work on a solid, level surface. Never jack a car up on dirt or grass.
- Check for any brake fluid leaks or cracked brake lines. Replace them as necessary.
