During a visual approach to Runway 28L in SFO; we received an RA. The airport was conducting simultaneous close parallel visual approaches to the 28s. We had the plane in sight on the parallel runway. They were slightly behind us and had been told to slow to follow us. The conflicting aircraft appeared to be established on the 28R LOC and was descending near the same rate and altitude as us. As we descended through about 1;100 FT; we received an RA to descend. We complied and ended up descending below 1;000 FT while below the glideslope. We saw the aircraft to our right and were clear of conflict and able to return to the glide slope by approximately 900 FT. We continued the approach and landed.
An ERJ-170 pilot on a visual to SFO 28L reported taking TCAS RA evasive action from an aircraft on 28R which did not slow as directed by ATC.
