When I brake , the car jump

Hello, I have a problem in my 11 BL , when I brake  the car starts to vibrate and jump like. It is as if brake drums  were off-center but I looked and I are fine. I changed the brake shoes and the new were biggest than the original . The original ferodo not full shoe. Has anyone had a similar problem? . Silentbloks could be the trapezoids?

Hi, i think your brake shoe is not a good part as genuine one.  This shoe must not be bigger than the original, Usualy Ferrodo cover half part of the brake jaw. May be it is the cause of your problem.

Hey guy!

Confirmed : It should be like this one https://picasaweb.google.com/1000244514 … 7749119106
I guess you are not able to adjust the right positioning with a longer one.

And ... Did you really re-adjust the brakes after the change ?

Hello

The problem is the silent blocks in the front cradle. When they wear out, the lower arms becomes loose, and you get the symptoms you describes.
I have seen this many times.
