Technical Question to cinq owner with rear disc?

[ycming]

Hey peeps,

This has always been a problem for me. The car do hold perfectly at 2/3 click totally solid.

But when you want to use the handbrake to lock up the rear wheel completely, it takes alot of effort!

Does anyone faces similar problem ?

I'll got a set of seicento handbrake mech to fit, hopefully this will solve the problem, or anyone got any other ideas ?

Thanks
Ming

Time to go hydraulic

Mine lock on solid after 2 clicks. Not much effort needed really. Think you have the lightweight alloy GT calipers too iirc, so maybe start going to the gym.

 

[ycming]

Dan, it is dead easy to get to 2 clicks. IT holds the car but at 2 click is not enough to lock the rear wheel up for handbrake turns (in auto-test)

I would love to do that, but i would fail MOT

 

[Dan]

I mean locked while driving

 

[Brooky]

Is it down to the pads and discs then??

Rc runs the ut rear brakes and I'm sure he has no problem locking the wheels up, or has he got a hydraulic h/brake?

Could always run a second set of calipers for a hydraulic handbrake. Or get some spot calipers to pass the mot

 

[ycming]

Yeah he is running, hydralic.

Dan, if i remember you extended certain part so the cable ran nicely?

Thanks

You can just retain the mechanical handbrake, but move it slightly. You are allowed a hydraulic handbrake for MOT as long as you also have a mechanical one.

If it's a road car you want a mechanical one anyway, else your car may roll away one day lol

dont forget were talking about cinquecentos here lol there not exactly know for there excellent handbrakes

See the bit where the cable hookes onto on the caliper, can that be removed and cleaned ?

Thanks

aye, held on by a nut, and then wiggle it off. will be a bit hard to wiggle off due to corrosion but whould come off fine

 

[ycming]

Ahh, i'll have a go at cleaning it up, and try the handbrake again!

Thanks
Ming

my handbrake is stupidly good, 3 clicks locks it up fully at any speed

it was only that good when the new cable was fitted and cleaned up around the caliper though, before that it was very average

Sorry, the actual bit that holds the cable can be removed, but cleaning that will serve NO benefit.

Take what I say with a pinch of salt, as I stripped the rear calipers about two years ago and have no pics to jog my memory:

The bit you want to remove is bolted on to a threaded rod, that is then sealed adn enters the caliper to apply the handbrake. Cleaning the part you mentioned will just be a cosmetic job. Otherwise you are looking at a caliper rebuild.



Remember that although the discs on the rear typically work better, that's due to the hydraulic action on them. There IS less surface area from shoe/pad contact and with a handbrake they WILL require more effort due to this.

It's not a problem for most people, but if you are a car park show-off or doing some proper driving, it will be more of a problem.

If you need it for auto test, you need hydraulic....that in turn will mean a bit of plumbing for a front rear split, and some serious planing as how to route it all

 

[Brooky]

Get a pedal box in there!!

I may have a diagram somewhere for the plumbing with the original m/c but with a hyd handbrake and a bias valve. Rc helped me out with it ages ago before I bought a bias pedal box

ming... fit a hydraulic hand brake but leave the normal one in... wont be hard. have the hydro sticking up so its easier to reach to

and if it gets in the way just make the lever detachable to for road use

I struggle to get my head round how to plumb that for a dual circuit system, any pointers?

Cheers

[craigb244]

no idea haha I thought you have hydralic setup?

No easy way. You still have to do a FR split and run a T line from the rears so not an easy job.
