A previous issue with the master cylinder had left the discs quite badly rusted and pitted. I was hoping they would polish up a bit once I got the brakes working again. Wrong.
On a recent holiday up north a loud scrapping sound alerted me to the fact there was no meat left on the brake pads. I managed to get a set up there, and fitted them before coming home. Checking them after the 4.5 hour drive home I found the inside or piston side had completely worn away again .OK I was going to have to replace the brake hubs.
I went to AL-KO and bought new hubs, bearings, seals, and pads. They gave me the new gav. hubs.
When fitting the calipars back on I noticed the outside pad, the floating one was jammed up hard against the disc. To me it seemed the gav. has added extra thickness to the disc, and also gives it a rough texture. .Both wheels are the same.
Anyway I took it for a drive up the road. After about 2 km smoke is coming off both wheels, let it cool down and take it home, more smoke. Give it half an hour to cool down and repeated, hoping to wear off the gav. Now maybe less smoke on the inside wheel, about the same on the outside.
There is some heat on the hub and bearings but not as much as I would have expected given the amount of smoke.
The question is do I have to try and wear the discs in as I have been doing, or is there something else wrong.
The calipars seem OK, and new pads fitted OK with the old hubs.
Any ideas anybody ???
