TR4 HANDBRAKE PROBLEM

[Willie]

Hi All,

           Today whilst out, the handbrake stopped allowing me to apply it.  Pull and press, the lever returns to OFF position. When I think about it, it began to be awkward to apply a few days ago.  Please will someone advise what has gone wrong. If I will need parts, a simple list of likely requirements will be greatly appreciated as it looks as if they are hard to locate.

Best wishes     Willie

Sounds as though you have a problem with the pawl and ratchet Willie, or maybe the linkage from them to the button. 

Parts 7, 14 and 15 here:

Something may have become loose meaning the pawl doesn't catch properly, or worst case it has worn or broken. 

[Willie]

Many thanks Rob. It’s item 7 which looks hard to get.

Revington have a second-hand part listed ref 107633SH  but it says please enquire.   You could also try the TR Shop.

Not overly difficult to make if you have the remnants to copy.

Stuart.

Thanks Rob & Stuart. I'll start with Revingtons.  I find them very good.

These rods are for the tunnel mounted hand brake not the floor/chassis mounted type.

In my case (https://www.tr-register.co.uk/forums/index.php?/topic/80104-tr4-handbrake-button/&tab=comments#comment-761376) the problem was a broken pawl-release rod.

I didn’t have any luck getting one from any of the usual suppliers, but I was kindly helped out by John Morrison who had a spare - at the time there was a handbrake assembly on eBay but it wasn’t cheap.

As Stuart has mentioned, it is possible to make one - 3mm piano wire from a model shop and using what is left of the broken one as a pattern is doable.

Thanks for the recent comments.  I'm waiting on a call from Revingtons tomorrow about a new item. They have exhausted supply of used rods. A check on Ebay shows one assembly at £70 with issues with the cap, and no evidence of a rod! No go there.

If your really stuck send me the remnants of yours and we could make you one up.

Stuart.

[Willie]

That's very kind of you Stuart.  If needs be, I'll get in touch

Hi Willie,

If you draw a complete blank I have one with a new ratchet and pawl fitted.  
The lever assembly is fully functional , no cracks in the tube or strengthener fillet.

 It has the threaded outer section for a TR 2/3 grip that the later sleeve type grip will simply slide/ fit over.

 The weird bracket….It is attached to a floor mounting that was intended for a now abandoned Austin 7 Special.  I will Just unbolt the lever assembly from the blue brackets if you are interested.  

The chrome is speckling in a couple of places  see photos.  You could whizz it up and down with the polishing mop to brighten it.

Yours for £50.00 plus whatever the postage is.

PM if you get stuck

Cheers

Willie, I have a fully functioning TR3 handbrake but the chrome on the lever is extremely poor.

PM me if you can't find another solution

Many thanks to everyone.  I have obtained a s/h unit from a fellow Register member.

Great TR'ing to you all                Willie

Could anybody help with this TR4 hand brake please. The lever wasn't engaging into the ratchet so I bought a new ratchet and pawl but couldn't get them to run freely in the handle. I now have the button and rod out in case the rod was bent out of shape. Does anybody know if the rod should be angled at the end or dead straight? Looks like it needs an angle in it to me but the more of an angle I put in it the harder it gets to thread inside the handle. Any guidance appreciated please 

Kind regards Richard
