Rust in brake lines

[netsurfer]

Continuing the process of waking my k1 SV650 up after 10 years in storage. :rolleyes:

While waiting for some workshop supplies to arrive, I decided to take the brake lines off as there was a buildup of rusty slime on the banjos and bolts as a result of water in the brake fluid.

Having gotten them cleaned, decided to strip the whole brake system and sure enough the other hoses had a buildup of rust in them too.

Was thinking of blowing them out with compressed air - any thoughts if this will be enough to get all the crap out of them?

Front master cylinder seems to be seized, going to have a go at stripping it tomorrow.

You might be safer buying new braided hoses, rather than trying to clean out the old lines. The problem is, you can't easily see if there's any rusty crud left in the lines, even after blowing them through with an airline.

I'm not sure if there are any solvents you can use either (I have a dim memory that methylated spirit can be used to flush brake systems through, but please don't take my word for it).

I'm with Craig380.Brakes are the only thing between you and the Headstone.Get new lines.

My 10 penn'th.

Don't try and fanny on. Replace the lines, master cylinder internals and the brake seals and boots.

It's your safety at the end of the day

SV K1? Are they the original 17 year old lines?
If so I think your question answers itself. Get new ones.

Also pull apart EVERY electrical connector and check and clean any corrosion.I do mine once every two years and use Switch cleaner

and then treat with ACF50

especially the the Main HT connector to the Regulator/Rectifier.

People often overlook servicing electrical connections but they are just a important as any other part of servicing and especially on motorcycles that have been left unused for a long time as the contacts suffer from corrosion.

Thanks guys!

Was trying to keep the costs down as I may need to rebuild/replace the forks which wont be cheap. They most likely are the originals though so I best bite the bullet and replace them! Any recommendations? High performance or fancy looks are not requirements :D

I had noticed a bit of corrosion on one of the electrical connectors in the under-tank area - will give them all a good going over before startup.

Unfortunately there were a few things which went against me when I parked the bike up, 1) I didn't think it would be off the road for so long so didn't give it a good clean and oiling and 2) I covered it to keep the dust off but the cover seems to have encouraged the rusting process.

The exhaust header bolts seem to be the biggest victim, hoping I don't need to take those out as one or two of them appear to have corroded away so badly that there is no doubt they will break off.

Subframe appears to be very rough in places too, until I get it out I don't know if I can salvage it!

Was hoping to upload some photos but still haven't been able to.

I agree with all the above, replace them for sure, anything that could compromise bringing the bike to a stop quickly should be avoided! I understand there is a cost element but very well worth it.

I have done a couple of videos on brakes, my channel is in my signature if that helps. I installed Hel brake lines which were great, as an alternative, another great British brand Venhill have given me a full set front and rear to do a video on, and I must say, they look really good.

Fork rebuilds are getting closer to the top of my list... I have seen a rebuild kit (seals, dust cover, new bushes etc) online for £40 + 2 bottles of fork oil for £15 so £55 total.

Word of warning.Fitting none standard brake lines without certification e.g steel braided outers are considered an,"Upgrade" and anyone considering this should contact their Insurance company before fitting them to make sure they are covered under their,"Terms and Conditions" otherwise it can invalidate the Insurance.

This may seem petty but it's not.In the event of an accident and an Insurance assessor can find anything to save the Company money,they will.It's part of their job.

Worse case scenario a 3rd part is injured.All hospital bills that may have been covered under a valid insurance are not paid and could lead to financial ruin for the holder of the policy.

I'm not,"Scaremongering" just laying out what has happened to some.

If in doubt,check with the insurance company.A few extra quid now can save a lot of grief later :)

A friend of mine had an accident on his gsx and the whole front end was damaged. They didn’t pay out as he had an aftermarket exhaust fitted, therefore it was an undisclosed modification so he got the whole bill!! I was not aware of mods like brake hoses coming under this as whilst exhaust may affect performance (increase in horsepower etc) brake line do not... made me think about making a phone call to check unless anyone else on here has done that already?

As I said Tamsen it's specific to the Insurer and Policy what they class as allowable mods.If you want to be certain it's best not to second-guess Insurers for the sake of a phone call IMHO.

Sort of on the topic of insurers.Last year I fitted a,"Slip-on" exhaust but also wanted to up my usable mileage so rang Bennets whom I was with to check and the exhaust was fine but I had to pay another £30 for the extra miles and of course their £35 Admin fee so my total insurance had now cost me £175 from the original £110.I was earning good last year so didn't mind.

This year's renewal from Bennets including the 1 year ,"No-Claims" I now had(I used to have Classic Bike insurance so had no no claims bonuses to use) came in @ £286!!!!!!!!!!

Same bike and conditions.


Sod that.Shopped around and got what I wanted all things declared from MCE for around £160.

Point being Insurance can be complicated hence my warning.Now I'm not telling anyone to do as I do but just giving fair information so they can be armed with info and decide for themselves.

Here's how I look at it.

With the work I've done on my SV and it's condition I value it to replace at around £2000 and if the worst should happen and it had to be scrapped because of an accident/theft etc not to mention any 3rd Party liabilities.

I'm not risking that 2 grand for the sake of an Extra £50 whatever and the cost of a phone call etc.


HTH :)

Hi Tamsen!

Your channel needs no introduction :) Think I must've watched all if not 99% of your videos by now :D

Fork rebuilds are getting closer to the top of my list... I have seen a rebuild kit (seals, dust cover, new bushes etc) online for £40 + 2 bottles of fork oil for £15 so £55 total.

That's good to know. I was worried about rebuilding them but after watching a video that Delboy did i'm pretty confident I could do it - looks easy :D Just hope that the surface rust on them is above the seals!

I've had a look at those HEL lines and think i'll get a full set of those, once I get the engine running and know there's no other problems lurking around the corner.

Wow! your lovely comment has made my whole night!

I am doing a fork rebuild video soon, my seals are slightly leaking so I figured it would make a great video!

The HEL lines are good, but I will compare them to the ones Venhill gave me to film, I have to say I am impressed with the quality of them. I went for blue so they would match the colour of the bike! Next Friday there is a video about revamping the petrol cap so it might be the week after that.

[netsurfer]

Great!

Will wait to see the brake line review before deciding which to go for.

Tonight I got the carbs back on but when I retrieved the tank from the shed I discovered it it very rusty inside 😭

Ironically, in your video tonight you mention about keeping the tank full if storing for a long time 😖

Going to go out to the motor factors tomorrow to see if I can get some sort of treatment to help with rust removal.

I think until I get the engine going I will put a hold on buying anything, in case there are any more hidden surprises!
