Hello,

Whilst going through the spares that came with the car, I noted a set of used front brake pads.......... then to notice they were most definitely wedge shape.

Looked up the code and saw that new pads are also that shape.

Why are they wedged as I have never come across that in 40yrs of classic car ownership ??

Regards.

Richard.

V4 brake pads have always been wedge shaped due to the design of the callipers being fixed to the Knuckle with a pivot on one end.
The upper pad in pics is off Morris 1100 :-

Thanks Woody.

I presume that over thousands of miles the pad levels out, or is it a case that the pads end their life still with the wedge shape albeit slimmer ??

From your link, not just applicable to the Saab 96.

Amazing, you never stop learning !!

SAAB96L.
If you calipers are working properly, they slowly pivot round the lower swivel pin, as the pads wear.
As you surmise the pad angle reduces, as they wear, and are close to parallel, by the time they are fully worn out.

Thanks Andy, that does make sense and yes it appears that the brakes are working properly. When I get the car in to the garage for its full strip down, it will be one of many things that will be checked.

Regards.

Richard.
