iget a frontend shake at high speed when braking. on 2004 Honda Accord

i also get a bump in front end when turning sharp at slow speed

Asked by for the 2004 Honda Accord
have the front end steering and suspension check. Trying to describe the components and what to look for, without you knowing how it works, you might miss something. Most shops will do an inspection and free estimate, ask them to be sure you won't be charged for the inspection.

Most likely the brake discs need either machining or replacing if they are too thin. Can't guess what your bump is.
