brake servo relocation

[cadetchris]

i am toying with the idea of disc brakes, just a case of getting them, but not to fussed if i get them or not.

[Fingolfin]

Then absolutely hold on to the servo...but I see no reason to have it in the car while you retain the drums.

Of course, one could fill many thick tomes with all the things I do not see.

[cadetchris]

humm. well i am going to shift the thing, its doing my nut in where it currently is, its probably not doing the carb and air filter any good by rattling off the servo.

[DaisyMayFozz]

remove servo, and if you decide to put discs on, then find a place then. right now it's pointless. fit Wolesley 9inch drums on front if you are concerned about stopping

[cadetchris]

excellent, job for tomorrow, out it comes, in the shed it goes and it means i can have a fettle in the engine bay without being hindered. so, slight problem now. what do i do with the little pipe into the inlet manifold? i cannot leave it uncapped as it will really mess up the mixture

[bmcecosse]

Plug it!

[cadetchris]

with?

[bmcecosse]

A cork ? Anything that snuggly fits the hose........ or get the correct plug for the manifold - 5/8" UNF I "think".

[charlie_morris_minor]

you could always run a bit of pipe of the manifold and put a spark plug in the end of the pipe.. not my idea the person that fitted the fiat engine to a car I purchased did it..

[cadetchris]

ill have a fiddle and see what works

[bmcecosse]

[cadetchris]

well my first thought the other day was to rip out the whole 3 branch exhaust (and the servo) and replace the lovely original exhaust and manifold. but alas, i dont have these original bits any more, so ill stick with the 3 branch and whipp off the servo when dad isnt looking

[MarkyB]

Disconnect and block off the vacuum hose, then drive the car.

Then make a decision.

You will need to recalibrate your leg for the difference without a servo, so will your dad if he drives the car.

[cadetchris]

sounds like a plan,

thankfully dad dosent drive primrose, i guard her keys against such eventualities

[cadetchris]

well having disconnected the vacuum pipe from the servo and blocked it, then given primrose a spin, the overall consensus is ill keep the servo, but just relocate it within the engine bay. i knew the brakes in original condition where a little vague, but good god, it takes twice as long to stop and even then you need thighs of steel to pull the car up to a junction.

ill keep the servo for the time being

[Fingolfin]

Really? This surprises me. But, hey, trust your experience -- I never put much stock in the 'lying eyes' argument.

[cadetchris]

i was truely shocked at the sheer effort it took to stop. i have owned and driven many cars older than my '69 morris 1000, but dear god it took some effort.

[bmcecosse]

Something sadly wrong with your brakes then......... Standard drum brakes DO NOT need high pedal force.

[cadetchris]

it it be the way they are piped up? the pipes goes from the side of the master cylinder, through the servo to a T junction. left goes to left front brake, right goes to another T junction, where straight on goes to front right brake and the remaining off shoot goes to the rear brakes.

[bmcecosse]

That's all ok - so unless keeping the non-functioning servo in the circuit somehow increases the pedal load (can't see how it would) I still feel your brakes are not in good shape!
