Default help: thump when braking or accelerating harder than normal

this happens much more noticably in the wet, although i can provoke the noise in the dry if i do a full emergency stop.

basically, if i brake hard enough i hear this thump from the front end of the car, the next time i accelerate hard i'll hear the same thump again. it's quite strange...

could it be an engine mount?

Could it be that your caliper is about to go?

If you are not sure then bring it to a mechanic.
Besides that I also had a thump like your describing and it turned out to be a front ball joint. cost 200$ to fix and the car was golden again!

Definitly sounds like it could be an engine mount. I'd check them out before I started pulling things apart.

is that the sort of thing that will go clunk in wet weather?

Back from dead. I get a slight thump when close to coming to a complete stop. And also when my wheel is turned completely to one side.

Bump!
