Hi All,
I'm trying to figure out what is wrong with the braking on a 95 Astra 1.4 (No ABS)... Braking is poor / spongy.
I don't believe that there is a problem with vacuum, as pumping brake a long time after engine stop indicates vacuum is still present.
I first tried bleeding brakes through, but this did not seem to improve braking at all - not even for a short time, and I didn't notice any air coming out during the bleed.
I was thinking of the master cylinder / servo, but does the fact that the bleeding didn't even temporarily improve matters eliminate the servo from the enquiry?
I don't know how may ways a servo can fail - it is usually related to air ingress to the system?
Anyway to get to the original point of the post...
I was going to take a look at the drums to see if there is some issue there - not really sure if they can lead to this symptom though.
I can't get the drums off though! They have presumably worn a lip on the drum, and I probably need to release the auto adjuster to get the drum off. How might I accomplish this? I see 2 rubber bungs in the back of the hub...
Under one of the bungs is a tiny plunger - which perhaps is something to do with releasing the adjuster. Doesn't seem to work - so not sure...
Can anyone make any suggestions about the overall braking problem, or my current problem getting the drums off?
Any advice would be greatly appreciated.
Thanks all,
James
