I'm going to be changing front brake discs and pads (having one rears already this weekend) on my Alfa 146 (1.8 TS plastic top). I found this nice guide
over at alfa145.com and read the relevant part of the service manuals, but still have a couple of questions that I hope you will help me answer. So, without further ado:
1. I need to be sure I understand this right: on the front calipers, before reffiting the pistons need to be simply pushed back, as opposed to winding them back (with a screwing motion) as is done one the rear calipers because of the handbrake self-adjusting mechanism. Is that correct?
(I want to make sure, because I have only a pushing kind of tool. Not realizing this difference between the front and rear calipers, I tried pushing back the rear caliper pistons - needless to say, hilarity ensued.)
2. Does the caliper support bracket really need to be removed in order to change the discs? When doing the rears, I was able to change them with the bracket still in place with just a bit of wiggling, so am wondering if I can expect the same when doing the front.
3. What are the metal springs on the outisides of the front calipers actually good for? Are there perhaps some holes in the front pads that the spring fits into, fastening them this way to the caliper and helping them stay in place?
Thank you in advance for any answers
