austin healey " E " brakes

After installing new rear brakes on my 65 BJ8 the E brake will not hold on a grade, the handle will come completly off the teeth, whats strange is the brake works just fine in a flat surface,2 or 3 clicks and its tight, the cable is ok, no frayd wires,no busted brackets,etc.even tighting the ajuster way tight gives little or no results, any thoughts out there?Mikkus.

Hi are you sure the btake shoes are properly asjusted to the drums and did you bleed the cylinders properly.???
OH one late thought the sliding adjuster pistons inside the break assembly can be frozen and not moving the shoes--Keoke

Hi Mikkus,
Are the bolts that hold the e-brake to the drive shaft tunnel tight? If the brake handle moves left-to-right, the teeth might slip off. Also, how good is the spring that holds the release button. Does the button require a fair amount of force from your thumb?

If it was working well before, I would adjust the square bolt again 'till tight then back off one flat. You should not have to adjust the cable if everything was done properly. Remember, it is totally mechanical. No hydrolics involved.

Mikkus,
The emergency brake bracket was not welded very good on my 65 BJ8 and would " slip off the end " when trying to set the E brake since it was only partially fastened to the frame.
I had to re-weld it to the frame. I also strengthened it with a little extra piece of metal at the junction between the bracket and the frame.
Perhaps the same guy welded your 65 E brake bracket to your frame ( on a Monday morning ) :crazy:

Mikkus -

You're very first mistake is using the "adjuster" to tighten the cable. I assume you are talking about adjusting the slack out of the cable by tightening the fork which attaches to the handbrake attachment under the axle? If so you are adjusting your brakes wrong.

You must slacken this adjuster off completely then take up any slack in your brake shoes by adjusting them per the manual (i.e. by tightening the shoes by twisting the square adjuster peg on the back of the brakes).

Once you have done this, then you can remove the slack out of the system by taking up the fork adjuster on the cable under the axle.

Also beware these cables break through the front mount located in the driveshaft tunnel quite easily. Fixing that mount in the tunnel is a b*tch.

Re: austin healey " E " brakes

The square nut that adjusts the rear brakes is the primary adjuster. The cable adjuster can override the square nut adjuster and end up with the rear brakes on all the time. If you cannot affect the rear brakes with the cable adjuster, it is not hooked up correctly.

I posted simultaneously with Alan (Healeynut), he is right.

Right now im tossing my xxxxx%^%D at Moss and there 3/4" to short pads,ill let you know, thanks ,Mikkus.

Re: austin healey " E " brakes

Having the original shoes relined is the best method I have found. However, the US lining and UK lining differ in thickness and some times you can not get the drum back on. So I would check the manual for lining thickness and tell the installer . Additionally having the lining riveted in stead of glued [ Bonded ] will reduce the brakes tendency to squeal , I also like to send the drums out too and have the shoes arched to the drums.--Fwiw--Keoke
