Re: Brake bleeding problems - silicone fluid

Well, so you say - but when I described the situation I had experienced with a hydraulic throttle on a bus - that it started leaking when I switched to silicone fluid & then gradually stopped again when I topped it up with the old stuff - Angus replied that this was "utter rubbish". I invited him to...

Re: Brake bleeding problems - silicone fluid

This seems to be turning into an argument between two camps, each of which is becoming ever more eager to prove the other wrong. This is irrational. Clearly some people have had problems with silicone fluid (myself being one of them). Others have not. Why should that be contentious? Supporters of si...

Re: Brake bleeding problems - silicone fluid

The fact that silicone fluid is not hygroscopic is not necessarily an advantage - water will get into the system in the same way it does with the old stuff, but instead of mingling with the fluid it will pool at the lowest points, where it can do even more harm. If you have one of those diaphragm th...

Re: Brake bleeding problems - silicone fluid

An interesting observation, but quite without merit. I had a coach with a hydraulic throttle. Switched to silicone fluid & it started leaking. Switched back to the old stuff & it stopped leaking. Nothing remotely dangerous, let alone illegal, in that. I think the two types of fluid are immiscible ra...

Re: Brake bleeding problems - silicone fluid

You have springs in your rear calipers? Are these the old Dunlop type? Just clamp off the flexi hose - that will soon tell you whether that's where the problem lies. If you get a good pedal, you have a problem with the cylinders.

Re: Brake bleeding problems - silicone fluid

I would just open the valve & keep pumping. You might have to hold the pedal down at the end while you close the valve. Also - here's thought - you do have an in-obstructed flow from the reservoir to the m/cyl I presume? Here's an article I just found from an earlier post - worth reading right throu...

Re: Brake bleeding problems - silicone fluid

If you had drum brakes this might be an adjustment issue. But discs rule that out. So there's air in there somewhere. Try clamping off the rear flexi hose & see what that does. At least it will tell you where the air is. In fact you could bleed it in stages - just crack open each joint from front to...

Re: Idiot Calling - diesel in E type

I have a feeling there is if you really think you need such a thing. Try eBay? Just to complicate matters, in England, gasoline nozzles are green and diesel are black, while in the US they are the other way round.

Re: Brake bleeding problems - silicone fluid

I was particularly advised against using it in the clutch system. Can't remember why.......... I just remember that it has no lubricating properties There might be a connection between these two, since the clutch seals have much further to travel than brake seals, so if lubrication is an issue, it ...

Re: Brake bleeding problems - silicone fluid

Well, that's a new one on me. I do know that the temperature at which diesel will spontaneously combust is lower than that of petrol/gasoline. My neighbour in Florida was convinced that the spare can of gasoline I keep in my trunk was going to combust in the Florida heat, till I reminded him of my H...

Re: Brake bleeding problems - silicone fluid

....Dot 5 will not absorb moisture. I can't see why it would attack seals as it is pretty inert, non flammable and won't eat paint.... 1) Are these DoT numbers the same in the UK as in the US? I have a feeling they are not. 2) I don't think anybody suggested silicone fluid attacks seals. I do know ...

Re: Brake bleeding problems - silicone fluid

Well, it leaks past them then. As I said in an earlier post, I had a pretty bad leak on a hydraulic throttle. Topped it up with the old-fashioned stuff till I could repair the leak, but I never did - it functioned perfectly for many years thereafter. I'm sure if your seals are in perfect condition i...

Re: Brake bleeding problems - silicone fluid

I thought the problem with silicone brake fluid was it's lack of lubrication properties rather than it actually degrading the seal materials. I've used DOT 5.1 in my cars. It's fine. Regards I don't think it will harm the seals - it just creeps past them, like anti-freeze does compared with water.

Re: Brake bleeding problems - silicone fluid

I don't like silicone fluid. I used it once, on a hydraulic throttle on a coach. It started leaking past the seals. As a temporary measure I topped it up with conventional fluid. As the silicone fluid leaked out and was gradually replaced by the 'normal' stuff, the leak slowly got better and eventua...

Re: Idiot Calling - diesel in E type

A bit late seeing this so probably redundant. I wouldn't worry too much - I reckon a Jag engine would almost run on diesel when hot, not very happily perhaps, so a bit of diesel left in the tank will do no harm. Might be problematic cold starting though. As to Christopher's point about the filter be...
