Have read loads here about brake upgrades, but I'm not asking myself about upgrades, simply for help to understand why my 2.0JTS brakes aren't as good as my previous 1.8TS - whether there's actually anything wrong that I can fix or whether I'm being too critical.....
It's a 3 year old 2.0JTS. I've had it for 12 months. I changed the brake fluid last year after suffering fade, but must admit I didn't go to the trouble of winding the pistons back into the calipers, so there could still be "old" fluid inside the caliper.
My old TS used to "grab" quite sharply even with light initial pedal pressure, whereas the JTS has little initial grab.
If you "stamp" on the pedal to invoke the brake assist system, it stops really well and brakes hard enough to cause the ABS to kick in even on a dry road.
If you're just braking "ordinarily" though, there's little initial bite and if you try to press harder on the pedal for more braking effort, there's little extra bite. (This is even on the first attempt to brake, so can't see this is a fade problem....)
Car passed its MOT last month and brakes in a straight line, so assume all four brakes are working OK.
It was however standing unused for a few months before I bought it, so I did wonder about maybe the brakes being siezed. It has crossed my mind to take the calipers off, wind the pistons back in to check they move OK and sand down the surface of the pads & disks in case they were "glazed" or contaminated with summat....
But - as its done sixteen thousand miles since I bought it and passed its MOT, I'd have thought that any idea of siezed brakes just doesn't stack up.
Has anyone any ideas? Don't want to go out spending hundreds on upgrading the brakes - just want to restore them to working as well as my old 1.8TS did (and that was standard too, as I owned that from new...).
As it works ok when the brake assist kicks in, I can't work out why I don't get as good a response pressing the pedal myself...
