Brake line

Rubber hose replacement for steel line. Fit great. Still need to bleed.

What I needed but...thought these were 3/8x24, they were 10mm or 7/16 end fittings

Glad I ordered as I had to cut a steel brake like amd had this in hand to replace. Being rubber saved me a lot of time making bends. Secured to axle with zip ties instead of rubber coated hold downs. PT prices are the best I've seen on the net. Being in canada, items listed on PT site I can't source here in ontario, canada locally. SUcks for me PT doesn't have a Canadian distributor, but overall I'm glad I found pacific trailers. This far I've rebuilt my upf actuator (master cylinder, reverse solenoid and now brake lines), all from parts from PT!
