Brake Line clean out !

[smclaren]

I'm working up to a brake overhaul (shoes, cylinder kits etc ) and was thinking about the brake lines.

Some of the braking issues I am having might be due to a slight blockage in the lines (diving to the left when under brakes when cold, then coming good after a while) and was wondering is anyone has some tips on cleaning brake lines out. Replacing them would be real expensive over here.

Thanks in advance for any tips/tricks.

Smclaren, I have used a glass jar at one end of the line full of laquer thinner, then I use an electric fuel pump to pull the thinner thru the line in to another jar it seems to work well on the metal lines.

the first thing that comes to mind is that you could blow air through them. unhook them from both ends and then blow air throguh them. but the pulling to one side is usually a wet brake pad. or a brake pad that has been wet at one time. but since it goes away while driving. thats probably not it.

I would doubt that the steel line is cloged unless you had a LOT of water in the fluid. Have you replaced the rubber lines? They absorb water from both sides over time and will swell to the point that they close up. Remember you are nout looking for that much flow, more pressure.

if you use the lacquer thinner be sure to run some denatured alcohol through after wards. A complete flushing of the old nasty brake fluid may help, might be some moisture is giving you that pull till warm up.

X2 on the denatured alcohol. Somehow the idea of lacquer thinner & an electric fuel pump in close proximity just doesn't do much for me
I'd bend the rubber lines & look for any checking that you might see. They can deteriorate from the inside & cause the problem you're having.
