Product details
A pair of stainless-braided rear brake hoses for the specified Porsche 911/911S original brake arrangement. Wilwood’s OEM Performance Flexline assemblies use integral application-specific ends and an outer protective coating.
These are the rear hoses. On the 1969 through 1973 911, each rear hose connects the hard line on the body to the brake line on the semi-trailing arm. With no steering load, the rear hose only has to follow the arm, so check its routing at full droop and full bump and look for contact with the arm or the wheel. The matching front hoses are part number 221-17910.
For matching factory-style brake connections. These are Wilwood aftermarket hoses, not genuine Porsche parts. They are a different selection from the hose kits supplied with Wilwood caliper conversions.

Check the original hoses
Compare the rear hose fittings, seating surfaces, brackets and routing with the parts on your car. Modified calipers, swapped struts or hard lines can change the hose requirement. Confirm the hose dimensions and end fittings against the original parts before ordering.
Installation and help
After installation, each hose must clear the wheel and suspension without rubbing, twisting or becoming tight through steering and suspension movement. Have the complete hydraulic system installed and tested by a qualified brake technician.
