Requests for Help and (Hopefully) Answers / Re: Rear Brake failure
« Last post by Rob B on April 21, 2018, 11:13:24 AM »
Hi Arthur. If the rear brake was working perfectly and suddenly stopped working with no drop in fluid level or visible seal leakage, it won’t be a calliper seal. If it has original brake hoses then look for a bubble in the outer jacket. Otherwise, yes, master cylinder seal is leaking back. Don’t be concerned about working on these brakes because they are the simplest and best available, in 1980! All spares available from Guzzi bits, Ducati or Laverda etc. Front master cylinders becoming rare now.

If you do still have the original hoses then I would throw them in the furthest bin you can find. They will be knackered and they will let you down, possibly badly! Nice black braided replacements available from Hell for example.

Bought a Hesketh a couple of weeks ago and joined the club. Hello will be at Stafford so Ill roll up on the H stand.

Well finally the weather turned and I finished all the detail work I needed on the bike (seat is a pig to open) however 10 miles into the run the rear brake totally failed. No evidence of leakage anywhere so crept home gently (or as gently as a 3,000 rpm tickover allows-mayeb I caught the cable when the tank was off) Not fun!

My suspicion is a burst seal on the master cylinder as the rear calliper was not that hot and seemingly not binding. Any idea part number ? I traced the calliper seal set to 98.5032.50 ...anybody confirm that is right?

2 hours after my ride and the brake is starting to have some feel again so maybe it is the rear calliper..any thoughts folks I hate working on brakes.

Hi Rob,

Interesting - shows how careful we need to be buying and selling bikes.

Good news is that Arthur has now got his bike and is learning about all things Hesketh.

The reg number is interesting as it was used by Hesekth Motorcycles at Eaton Neston on a development bike.
Nice thing about Heskeths, they all have a story to tell.

That is good news indeed. I don't think we ever stop learning about all things HESKETH...  :D

Hi Arthur,

I'm not sure if this helps, but I suspect not. Hope it resolves itself as I was also interested in buying that bike.

All the best,

Hi there 10 days ago I bought this black bike. At least I thought I did. Paid in full now the dealer is avoiding me and I suspect trouble ahead.

I know it was on sale or return and do not think the owner was a member but anybody recognise it. Frame 013.

Good news Chris. Mk1 and Mk2 Golf both the same apparently. So there shouldn’t be a shortage of them just yet....

Maintenance, Repairs, Upgrades and Improvements / Re: Leakey rev counter drive
« Last post by Rob B on March 01, 2018, 01:04:44 PM »
Hi Chris,

One thing to remember when using the camshaft bearing jacking screws is to check that the respective camshaft is "off cam". In other words, the cam lobes are facing away from the buckets. Can be done by removing the plug and checking for TDC on compression, not on valve overlap. Other than that, I always use automotive clear silicone for all jointing faces on the Hesketh engine, just as they did in the factory - not bathroom sealant though, although that actually works too :-)  Proper motorcycle engineers will cringe at this but the cheapo clear silicone snot simply works whereas you can spend a fortune on Rocol Hylomar, STAG Wellseal, Heldite and all manner of other fancy stuff that simply won't work with a Hesketh engine.

There is a lip seal inside the right-angle rev-counter drive unit which always leaks so the best thing is to also use a bit of the clear silicone when tightening up the cable nut. Oil then travels some way up the inside of the cable but never seams to make it up as far as the rev-counter, except after a very long run...
