Review: I was doing brake work on my truck and its 20 yrs old and I was doing calipers and flex lines already, so I figured heck, the master cylinder can't be far behind and its pretty cheap to do, so I ordered this part. Direct replacement and with the bleeding kit (sold separately) I did the "bench bleed" on the truck which for me was easier, however still required two people to see when it was done bubbling. My new brakes are awesome, the pedal is high and hard, no mushy pedal! I'd recommend this part and doing replacement as I did if your vehicle is old and the existing fluid looks crappy and dark. The brake fluid is hydroscopic and adsorbs water from the air, and that is a cause of corrosion to everything in your system - ABS pump, calipers, master cylinder. Review: My truck is 23 years old and the brakes were getting soft. Replace brake pads and rotors and the last item was the master cylinder. After reading how to bleed the master cylinder before installation, I installed it into my truck. took about 20 minutes to installed. Then took the next 90 minutes to bleed all my wheels. Hardest part was getting to the brake cylinders under the truck. Once done, it worked perfectly. Brake are feeling harder and stops as expected. Good product for my Chevy Truck! ## Features - Precise replacement - cylinder housing is constructed to match the casting material of the original part and ensure similar performance - Durable design - all rubber components are made of quality EPDM compound for resistance to glycol-based brake fluid - 100% new - made entirely of new materials, not remanufactured, to ensure highest quality and safety - Strict specifications - made to meet rigorous SAE International standards - Ensure fit - Input your vehicle into the garage tool and check Confirmed Fit bar at the top of the page.

Normally, your master cylinder is filled with brake fluid. When you press the brake pedal, the hydraulic pressure in your brake system increases, which forces the calipers to grab the rotor or the shoes to engage the brake drums. If the system fails while your foot is on the brakes, it is possible that your system will remain locked in an β€œon” condition, causing your brakes to stick. Though rare, this situation can occur as your brake system fails to release its components and the brakes remain in an β€œon” condition. Also, check to make sure your caliper pins are also greased and the boots are not damaged, I have seen them actually rust and seize inside the housing causing sticking brake problems as well. **Q: Will this work with 4 wheel disc brakes** A: Yes. Used it on my 2000 Chevy with 4 wheel disk brakes **Q: does this fit a 1999 jeep wrangler?** A: This fits my β€˜02 Chevy Tahoe. **Q: 88 suzuki samurai master cylinder, which part number?** A: REGISTER YOUR VEHICLE WITH AMAZON AND THEY WILL TELL YOU. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by D***Y on 9 April 2022* I was doing brake work on my truck and its 20 yrs old and I was doing calipers and flex lines already, so I figured heck, the master cylinder can't be far behind and its pretty cheap to do, so I ordered this part.

Good product for my Chevy Truck! ### ⭐⭐⭐⭐ Review *by J***C on 9 November 2022* Great upgrade for any 88-98 Chev or GMC. Finally I have brakes as good as a brand new truck, no more spongy/soft pedal. Only reason I didn't rate it 5 stars is the price was a little on the high side. . but we always pay alot more in Canada. ## Frequently Bought Together - Dorman M630031 Brake Master Cylinder Compatible with Select Cadillac / Chevrolet / GMC Models - Dorman 13911 Master Cylinder Bleeder Kit - 22 In.
