    I used already elastic pads some years ago and have not been pleased.

     

    …but were they 3M? Like all things there are differences in quality which translate to performance. 
    They are cheap and easy to fit. Give them a try.

    Sorry, I don’t want to have elastic material between pads and pistons.

    I understand your point but you don’t need to be concerned. I have all braided hoses and even with the backing pads and silicone fluid there is no noticeable sponginess. 
    The change from rubber hoses made the most difference.

    Hi,

    currently the Mintex 1144 pads are annoying me very much with often (not always) very loud sqeaking on low speed braking,

    for example rolling in a traffic jam or to a red traffic light. This is mostly in town / village and pedesrtians pedestrians notice me negative.

    Any idea?

    Ciao, Marco

     

    These worked well for me Marco

    I’ve copied this from an earlier post:

    As for the 1144 pads - much better than standard search for MGB633 1144. You will get the ones with the smaller holes for the pins but it takes no time at all to enlarge with a drill. Far cheaper than seeking out the less common large holed pads. (Not sure you can get them with 1144material)

  10. Daylight running lamps

    in TR4/4A Forum

    We have front only daylight running lights in the UK as it makes the brake lights more discernible than they would be in daylight with just an increase in brightness when the tail light is illuminated.

  11. TR4a Rear Hubs.

    I’ve heard that the 4a half shafts are stronger but no one has been able to explain why. 
    The TR4 ones are machined down from  large diameter stock leaving the bearing abutment with a radius blended into the shaft. 
    The 4a shaft is made from stock the diameter of the shaft with a bearing sleeve shrunk on after machining. 
    I assume that they are made of the same material and given that the weak point will be at the machined taper and the spline root I can’t see why the 4a shaft would be any tougher. 
    With my production engineer hat on it looks like a cost saving change. 
    A case of “ the emperors new halfshafts”?

  16. Gearbox oil

    in General TR Technical

    All gearbox oils foam when cold and it can take a considerable time driving under load before the oil gets hot enough to let the air settle out…..much longer than it takes for the engine to get up to temperature. 

    I’ve bench tested a gearbox with different oils including EP90 and 20w50 engine oil and found that Penrite GB40 seems to foam less than others.

    I’ve found that heating the gearbox casing to around 40 degrees with a hot air gun  reduces foaming when bench testing. 
    It takes for ever to get any heat into the gearbox just by running it without any load. 
    Im guessing that your gearbox had been run for a short time prior to draining. 
     
     

  20. Steering Rack - Premature Wear ?

    in TR6 Forum

    Posted

    I don’t think that those racks are easily dis assembled. When I was looking for a TR7 rack for my rack and pinion conversion a friend who had an Argentinian one to hand let me partly strip it and I seem to remember that it has swaged on drumstick ball joints so I sought out a second hand original unit which was easily stripped for modification.
