Hey peeps,
Sorry it's so long, please read though, you may be able to help me!
Following on from the last episode regarding my CTR's dodgy brake caliper, and the replacement thereof, it seems that there is an underlying issue that was (possibly) the reason for the initial caliper failure, although I'm not sure how it is linked.
Before the caliper seized up last time, there was an audible low 'pulsing' sound coming from that wheel, which I thought was either the bearing, or the seizing caliper momentarily contacting the disc surface during every wheel revolution.
After replacing the caliper with a new one, the sound continued, and I put it down to something else (thinking that the new caliper would have cured the sound if the old one was infact causing the pulsing noise). However, yesterday SWMBO was driving us somewhere, and that wheel area started squealing loudly without applying the brakes. We stopped the car and I checked the NS front disc, and found it to be much hotter than the OS side disc. I also noticed that brake fluid was weeping from the caliper bleed nipple area (which I have sorted - the nipple was a teensy bit loose - a 1/4 turn sorted it).
I took the car out this evening after SWMBO complained that it squealed on her way to work, and gave the brakes a good workout, and indeed managed to get the squealing to start again.
After my blast about West Sussex, I stopped at work and measured the temperature of all 4 discs:
NSF=90C OSF=65C
NSR=40C OSR-120C
As you can see, the NSF and OSR discs are hotter than the others by quite a way. Now bearing in mind the braking system is 'divided' into two sections, one part operating the NSF and OSR and the other the OSF and NSR, I believe the servo (or whatever it is) is causing trouble, or maybe something else related?
Any thoughts, and is it likely to be £££££££££ to fix?
