## Questions & Answers

**Q: Please advise the sizes of the front and rear brake line ports.**
A: Yes front port for rear brakes. You could swap them with no negative effects, but the forward fluid reservoir is smaller to be used with drum brakes. I put disk in the back and works fine, just check the fluid every 3000 mi.

**Q: Will this fit 1989 v1500 blazer?  jb5 brake system?**
A: go to ACDelco website to confirm exact replacement part

**Q: Does the master cylinder come with brake bleeding kit (fittings and tubing?)**
A: Honestly, no just the master cylinder.

**Q: I c this all the time. It says in the description that this is vehicle specific, and then it doesn’t specify or give a list of the “Specific Vehicles”**
A: study the page closer, you have option to enter your vehicle info, then the item will have a area where it will say fits your application ot search for item to fit.
