OEM quality
OEM fitment and fixed my sinking brake pedal on my 95 Grand Cherokee 5.2! Just have to purchase a bench bleed kit separately.

Direct replacement for my 99 Cherokee XJ
This is a direct-fit replacement for my 1999 Jeep Cherokee XJ. Installed with no issues, appears to have solid OEM quality. Great price too - I’m sure I would have paid 100’s of dollars if I had a shop replace.

Great OEM Replacement Part
Replaced an original master cyclinder on a 2001 Jeep XJ. Came with a bench bleeding kit/instructions, new fluid reservoir cap. Does not come with mounting nuts. Perfect fit and now the brakes work great.

Best price
Used this on my '89 Cherokee for ABS conversion. Fit perfectly on matched power booster. Brakes work. Definitely bench bleed this because of the angle of the MC once installed. Be aware, the front brake reservoir goes dry alarmingly quick when manual bleeding. Does come with MC base sealing O-ring. Did not come with bench bleeding kit. Best price around.

Fit perfectly.
Follow directions closely for install, once it was bench bled it installed easily and is still working a few thousand miles later.

Works Perfect
Brakes were really squishy, like had to floor them. Installed this new master cylinder and brakes are great again!

Wtf guys
Purchased master cylinder and when arrived didn't have the plugs needed to do bench bleed. Had to go all the way to the hardware store 20 miles away where I spent 8$ on overpriced bolts to do the job. Then bolts allowed air into cylinder so I had to use Teflon tape which I then had to painstakingly remove with tweezers after the job. It was just a little mistake that cost me a lot of time and effort. Took 4 hours to do an hour long job. Wtf guys

Producto llegó bien y a tiempo. Sello entre el contenedor de plástico y el cilindro venía defectuoso y se sale el líquido por ahí en cantidades pequeñas. Recomiendo comprar de mejor calidad piezas para los frenos
