After some advice.
I have recently had a blitz on my wife's car and sorted out a number of problems (some of you may have seen the threads). I thought I had everything sorted on it (Vectra SRi 2.2 Direct - 2004).
One of the things I looked at was the brakes, as the handbrake wasn't the best and there was some squealing coming from the rear. I basically stripped each brake cleaned the pads & disc surface's and re-installed each, coating the rear of the pads with Copper Grease. All the pads & discs are genuine VX and are in very good condition (rears only done 9k miles - fronts approx 15k miles). The Rear pistons twisted in perfectly (using a caliper rewind tool). The result was that there are now no squeals, the brakes definitely feel better and the handbrake (after a few days) is excellent.
However.....my dad has a Vectra Design 2.2 DTi Automatic, also 2004. The other day I briefly drove this and the brakes on that are amazing!!!! Very keen and perfectly weighted. In comparison, my wife's car feels like it has a very 'long' brake pedal. They work fine, but just a lot of initial pedal travel compared with my dad's.
1. Are the brakes on an automatic / diesel a higher spec than on a manual / petrol?
2. If not, what could be causing the long brake pedal - everything seems in excellent condition in the braking system?
A few years ago I have had several Vectra C company cars (2.0 DTi's) from new. I noticed on these, and once on a loan car through the fleet workshop, that there was noticeable difference in pedal feel between them - all were LS model's & manual. The supervisor told me that some of the Vectra C's simply didn't have 'as good a pedal feel as other's, and that they never got to the bottom of why - although the brakes always worked very well'. What are other's experiences - is this true and simply the luck of the draw or is there something wrong?
