Just a thought- But I have worked on d21 and d22 breaks that both had the same shite breaks! Did the lines (braided) and that gave a better harder feel but still shite and felt like you had to stand on 'em to get them to work.
Anywaysss - with both cars I noticed that the front rotors had heat marks on them. So out with the callipers, both lower pistons on both cars had ceased ! the d21 needed a new piston and seal kit and the d22 just the seal kit. Water and crud gather at the lower piston and it will cease -leaving you with just one piston doing the work of two...
Changing fluid is good -sure "and should be done" but unless you are cleaning out the lower piston your only doing half the job.
I have always wanted to drill and tap a drain plug into the callipers- if you look at the callipers air bleed screw position you will notice there is a spot at the lower end where this could be done... it's the only way to make servicing the fluids practical and thorough
Sooo that done - better, muuuch better! fukc I nearly head butted the steering wheel in the d21
the 22 not so much- good quality H/D pads and slotted rotors fixed that- you can actually see the nose drop when you hit them now- brilliant!
I know bugger all about d40's but i'm betting they have the same callipers as the early ones?? got a pic for me???
It's not a hard job doing brakes you just have to be thorough and spotless when assembling them- I was shown as a kid so if it's your first time I suggest you pay a mechanic to work with you and step you through it - there's some tricks to getting those pistons out and then back in with the new seals.... keep us filled in , cheers vic
