87-90 Wrangler YJ Power Brake Booster Master Cylinder CJ CJ5 CJ7
Wrangler YJ power brake booster with master cylinder in very good condition. Tested and works perfectly. Surface rust, but solid for use. Fits Wrangler YJs 87-90. Will not easily fit into later models because the hole on the end is a different size (see closeup). Can also be great for converting CJs 76-86 to more powerful setups.
