[Triumph cars Glycol DOT 3, 4 & 5.1 Vs DOT 5 silicone brake fluid]

Triumph Stag Master cylinder Silicone brake fluid fail:

 

I have discovered an issue using DOT 5.0 that those switching to is should be aware of. If you have recently purchased a new Master cylinder or a new Master cylinder repair kit you may discover as I did, that the rubber components are not compatible and the unit will fail with less than a years use or within 950miles.

 

The issue seems to be that the manufactures are currently making the rubber components out of a material that is only compatible with DOT, 3, 4, & 5.1 not 5.0 If you are lucky to have an original Lockheed rubber kit you are safe, if not you may notice silicon brake fluid seeping from the underside of the brake servo unit.

 

In my frustration I have had the kit re-manufactured in EPDM which is specifically engineered to be used with silicone brake fluid.

If you wish to purchase the kit, I am currently selling them on eBay.

For anybody thinking of using Glycol-based brake fluid, please see attached photo of my Vitesse bulkhead after 24 years of using Automec silicone DOT 5.

Hi Andy

If the paint job is poor, expect filler do try to check the usual places with a magnet in your hand (you'll get a light feel where there is no Steel).

I'm sure the price quoted does not include any repairs to the metal, these cars rot from the bottom up. This may sound obvious but there,s no point in having a smashing looking car that is a death trap.

Have you contacted your local club to see if there's any one that can come over to look at the car to advise whether its worth the investment?
