Cleaning Brake Lines Internally?


Recommended Posts

Richard if this is for the 300ZX project and the lines look suspect I would replace them new ones or make new ones . Having spent 10 years or so in the hydraulic industry with sort of thing it is not worth the risk of failure . But I did use prep -sol as used in paint surface preparation to clean parts . Only ever used abrasive on cylinders if they had radial scoring . Any thing else was a throw away and make a new one.

Will blow some metho (sans raspberry cordial) though the lines and take it from there, if they are dirty then they will be replaced. I have seen new brake lines split so there is no rush to get new ones, flexible hoses yes, replace those with braided.

You are kidding! ( not at all surprising, we all suppose,,,,,)

Exposed to atmosphere, no matter how you think you drained them, the hard lines will have brake fluid remaining. Atteacts moisture, bare steel bundy tube, there will be internal rust.

Refilled, and used, you'll get a constant supply of rust particles dumping into your calioers, and chewing out your piston seals.

 

Just replace the bundy tube with fresh, a Sykes-apickavant double flare kit around $100, and a small diam tube bender, along with plastic coated P clips, fixed

Jason, you need to keep up with modern technology, a fibre optic micro camera is going to be inserted in all the hard lines to check on their condition.

 

Chuckle.

 

Actually the lines were drained  as soon as they were removed and have been hanging up in the shed so they could continue to drain, the fluid looked good with no sign of contamination. But they will probably be replaced anyway, will have some metho run through them to see.

Try pressure pumping walnut shell, hand cleaner through them. The non solvent stuff. Diaphragmatic pump or piston.

 

Then to be flushed thoroughly with solvent, of course......

Try it out on small scale first to ensure desired results are achieved...

Or otherwise sand from lake McKenzie, fraser island in a sand / water slurry.

Lol just got back from holidays ????
