But whenever I hit the brakes hard the vibrations stop and it feels like normal. It only appears when I brake in small amounts.
Do I have warped brake discs?

Yes, sounds like some slight disk warping and the fix might be an easy no effort, no cost one.

Take the car on an open, but little used fast road, where you can safely get it up to 70 mph and brake very hard (just short of the ABS being triggered), several times in succession.

The idea is to get the disks good and hot, but not come to a complete stop, then rapid acceleration again to 70 and repeat. Do it two/ three times and it may just fix the issue at no cost. Remember you must not come to a complete stop with hot disks, because that will cause distortion.

Fix a poor handbrake; DIY ABS diagnostic unit; Loan of the spanner needed to change the CDT belts; free OBD diagnostics +MAF; Correct Bosch MAF cheap; DVB-T install in an ex-hi-line system; DD install with a HK amp; FBH servicing.

I've taken a vow of poverty. To annoy me, send money.
