Update
1. Rebled the System - no Change recorded.
2. Bypassed the break servo, re-bled the System but the amount of leg effort to stop the car is very little if at all different from before.
In bleeding the System however, sometimes it seemed like the brake pedal was relatively solid even though a bleed nipple was open. Then having released the pedal and having another go, it was easy to push to the floor again and expel the fluid/air into the jar. I am wondering whether the pushrod or mechanics inside the MC are jamming, hence the amount of effort required.
As before the car does stop but you Need to stand on the pedal ( which at least is very firm and not at all spongy) to get it to do so. The wheels, contrary to other Posts I have read here, are nigh impossible to get them to lock and let the tyres skid.
This is pointing me in the direction of ........ I do not know what?
To summarise :-
1. firm hard brake pedal - no pumping required. Thus no air in System and MC is working.
2. A lot of leg pressure is Needed to give the feel that the car is decelerating. In fact, initial breaking does not seem to have any effect at all and only when you apply more pressure does the car slow up.
3. The 50km/hr brake test, which should to all accounts lock the wheels, does not happen.
For my logic, I am back to the theory of the front pattern cylinders not transmitting enough oomph. Then again, could it be that the old MC, despite the firm pedal, is not producing enough pressure. As I write this I remember that the reason I replaced the front cylinders all round 3 or 4 years ago was because the left side front wheel would then lock easily but the right side not, causing uneven braking. Frightening it was!
