240 240 Estate brake issues
Hi chaps, I've noticed that the brakes have been getting spongier over the last few months but because my P plater son has been driving it it's been out of sight out of mind. I hopped in it the other day and after driving it to the shops thought it needed further investigation: jacked it up and checked the pads all round, there was probably around 60% left front and rear so that checked out OK. The fluid level in the master has remained constant for as long as I can remember but I know the old girl hadn't had a fluid renewal for a very long time so thinking there might have been moisture accumulation decided to do a flush.
I haven't got a relevant manual for this model so just went for the top bleeder nipples figuring there wasn't air in the system (no external leaks anywhere etc) and got my son to help me, I had the end of the bleed tube sitting in fluid and worked my around the car from furthest from the master to nearest. topped the fluid up as I went but no change in the pedal feel once the car was started.
My son is 6'7" and was a tad heavy-footed in pumping the pedal as he hadn't done it before but I made him take it really easy after the first number of strokes. Long story short, I was running the torch around trying to scope out what was going on with brake lines etc after this and noticed fluid dripping from the sensor seal on the distribution block (see photos). I disconnected the boot and connector from the sender and gave it a very cautious tighten thinking it would probably be OK but since then the master has been losing fluid although it's still topped up enough to not suck air but the sensor seal has continued to leak under pressure and the Brake Failure light comes on.
I guess I have a few questions:
1. Have I rogered the sensor/distribution block and need to source another?
2. Is it worth pulling it out and trying to reset?
3. After reading various posts on the forum is it likely that it's the flexible brake lines that were the culprit all along?
4. I've got a pair of new rotors coming from Fleabay and am hoping they will give a bit more braking effect once fitted, has anyone used these before? https://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItemVersion&item=253972377412&view=all&tid=2371214482015
Any help gladly appreciated....
