Hi all . I'm wanting to upgrade my brakes on my ke20. To fit ke30 backing plates with girlock calipers I need to retap the holes in the strut that mount the backing plate. As I have no real correct tools to measure can anyone help me with what size drill but I need to drill them out and what size tap I need to retap the thread . Cheers

Scroll down

Or use the Ke20 bolts and position the backing plate so it won't rotate when you hit the brakes going forward and do the bolts up TIGHT. Before I get angry responses, this was done to a competition car and never caused any problems over a number of years service :)

 

Thanks heaps

As listed in my walkthrough posted above 10x1.25 is factory ke70

 

You can tap to 10mm thread size and use bolts that thread

Thanks jono . So I get different bolts to the ke70 ones? And the bit I use to tap is 10x1.25?

You can use ke70 factory bolts or if you buy some from nubco in say like 10x1.5 or 10x1.75 then just use the tap that matches

 

You can buy bolts in different threads
