BrakeQuip

TESTED FOR SAFETY

Most automotive brake systems operate between 850 and 1050 psi. Every BrakeQuip brake hose is pressure tested to 3000 psi prior to sale to ensure safety and performance, even under panic-stop conditions.

Hose Expansion Test Results:

The Society of Automotive Engineers (SAE) categorizes brake hoses as regular expansion or low expansion. All BrakeQuip brake hose products are low expansion, as verified periodically by testing from an independent lab.

Per the SAE J1401 standard, low expansion hose cannot expand more than 0.33 cubic centimeters per foot of hose length at 1000 psi. The most recent test sample of BrakeQuip rubber hoses had an average expansion of 0.11 cc/ft at 1000 psi, with individual results ranging between 0.10 cc/ft and 0.12 cc/ft.

Similarly, the most recent sample of BrakeQuip braided hose had an average expansion of 0.07 cc/ft at 1000 psi, with results for individual hoses ranging between 0.05 cc/ft and 0.11 cc/ft.

There are additional thresholds for other pressures. For example at 2900 psi, the allowable expansion for low expansion hose is 0.61 cc/ft. Our test sample of rubber hose averaged 0.30 cc/ft, with a max of 0.31 cc/ft. Our test sample of braided hose averaged 0.11 cc/ft, with a max of 0.15 cc/ft.
