Ok guys, got a coupe of questions I'd like to pick your brains about.

Firstly, had the car inspected by a vehicle inspector before buying it and he gave it the all clear and said the little bit of sludge I noticed in the oil cap and engine wasn't anything to worry about, just get the engine flushed and change the oil. Another mate who's fairly familiar with these cars said the same thing, but just thought I'd throw up a coupe of photos and see what you guys reckon.

So this is AFTER having the car serviced by my local Honda dealer and they apparently did a flush. Would you guys feel this is worth being concerned about? Or just flush the motor and change the oil a few times over the coming months?

Oil cap:


Inside engine:




There's no sludge on the dipstick, the oil is nice and clean on there when I pull it out.



Also, had a stereo fitted to the car (coupe of digital amps) and have since had the battery warning light coming on on the dash, even after having my trickle charger attached to the car all night and battery being full in the morning. Is this most likely to be a dead cell/old battery in need of replacing? Any suggestions for a decent replacement (deep cycle?) battery for these cars?

This is the battery that's in it, if that helps:



Oh and the front pulls to the right when I'm braking, which I've read elsewhere on here can be a symptom of screwed rotors, which mine look to be (big line/gouge in the middle).

Also need to replace the rear pads, so I figured may as well do all rotors and pads at once, give it a bit more bite. Ordered some slotted DBA T3's for the front and some of the older style slotted DBA 4000's for the rear (they were cheaper than T2's), now just need to sort some pads. From what I've read on here and elsewhere QFM HPX or EBC Redstuff are pretty good options? Does anyone know the part numbers for the HPX pads or the redstuff for my car and suggestions where to buy them online from?
