Brake Master Cylinder for Jeep Wrangler: Natural Rubber
This brake master cylinder for the Jeep Wrangler is specified around natural rubber, which decides how it behaves in service far more than the part name does. We build to a written specification — base material, dimensions, finish and packing — and hold that specification on file so every reorder reproduces the approved piece.
The usual reason a programme changes supplier is not unit price. It is lead time that slipped twice before bulk started, or warranty claims traced back to a single lot. Both are specification problems, and both are preventable.

Questions buyers ask
What happens if a lot fails inspection?
The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.
Can you match an existing sample?
Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.
How long does sampling take?
Samples leave the factory in 10 working days, and each revision round adds about 3 days once you have seen the first piece.
What is the minimum order quantity?
The standard MOQ is 1000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
Send the specification you are working to and we will confirm what we can match, what we would change and why.
