Vented disc?

[PaulB]

Just wondering if anyone managed to fit a vented disc with original caliper, using the standard Stag 14inch alloys? If so can I have details?
Thanks.

No cant be done safely there's not enough room to get a vented disc in the caliper.

[PaulB]

How about spacing the caliper?

[Goldstar]

I think Bullstarz means there is no room inside the caliper (between the pads) for a vented disc to fit?

[bullstarz]

The disc has to fit in the caliper (red arrow) and the caliper splits on the blue line.

I have 3 Stags as you do on my first Stag i had spacers made for the brake calipers and the disc,also had the open space machined out,when talking to a couple of guy at a show the Tr6 people do the same thing Rimmer at one time made the spacer for Tr6 calipers,on my 2nd Stag I used the wilwood brake set up as I bought the calipers second hand,and only had to buy and machine the calipers mounting bracket,,on my 3rd Stag I'm going to use Mondeo calipers and get a mounting bracket made up

If you look in my photo's your see some of the machined bits i had made

one might enquire as to why you need vented discs and original rims.

Guessing that you are not into racing so again I am guessing the car is predominately for road use.

Not yet had an issue with my stag brakes being unable to stop me. Locking the fronts up can be an issue on really aggressive braking which I can avoid by reading the road ahead. BUT if lets say I wanted to improve braking performance and my stag original setup was bang on... then I might look at stickier tyres.

Cheaper than vented discs for a standard stag being used on the roads

Following on from a recent thread on the illegality of fitting certain spare wheels in case of a puncture, I must frankly admit amazement at the "apparent"* desire to knock up some home made DIY front brake solution and put the vehicle (again presumably) on a public road.

Apologies if I've got this all wrong, but the question wasn't "does anyone know of a company which can provide an upgraded braking system?". Again apologies, as it might be a background to a university engineering degree project to measure brake effeiciency differences due to fitting different discs or the like.

Standard Stag brakes are perfectly able to lock up all 4 wheels in an emergency. This photo shows what is possible at 60mph on a dry road with new GoodYear 195/65x15 tyres. Didn’t stop me hitting the truck though......

Hi, If your using your stag on the road only, whats the point of vented discs and 4 pot brakes as you will only lock up wheels under hard braking just as original do. To improve your stopping lenght ABS is the way to go. Can it be done???.

[dasadrew]

That's a new one on me that ABS improves the stopping distance!

[fussydave]

Agree with you both DJT TJK, no matter what they teach you about cadence braking, when an emergency arrises your foot goes down on that brake pedal like a pile driver and the only way to reduce the stopping distance is with ABS. More powerful brakes without ABS will only increase the risk of early lock up and extended stopping distance.

I've been sat here muttering "must resist urge to ask about modified brake systems and insurance regarding Type approval and Construction and use liabilities" wait for Drew, wait for Drew...and with one bound he enters the conversation lol.

Speaking as a racer of TRs the first thing you do is to remove your brake servo...it's too easy to overbrake when you are in the middle of 6 or 7 cars entering a corner and the car 6 foot in front out brakes himself amongst a smoke cloud. I guarantee you will have no trouble locking the brakes without a servo...and that's on sticky tyres, Triumphs standard brake offerings across the range were pretty good on brakes after discs entered the scene.
Admittedly the brake effort increases markedly but as pointed out it's purely a increment of desire to stop ! and taking the instant servo response away just allows the brain to overcome the chimp in charge of the car and find the biting point of brakes and balance it against the coefficient of friction of the tyres. The McLaren F1 road car is non assisted on brakes "to improve driver feel" I believe they say.

Morning all,
Phew! Right old can of worms this one.
Like most of the systems on the Stag (engine.transmission,suspension etc.) they are "of their time".
However, times change, as have driving conditions and traffic density.
Also included in changes are the sometimes awful standards of driving encountered.
"Driving ahead" which I like to think I practice, sometimes cannot combat the sheer stupidity encountered.
Coming back from our Drive it Day run, I was travelling in lane 2 of a local motorway. Slower traffic in lane 1, following a marked (local) police vehicle.
I spotted 2 "boy racers" (5 series BMW and "everything black/lowered/" grungy old Audi A3) flying in lane 3. Estimated speed in excess of 85-90mph, possibly more.
They obviously weren't "driving ahead", neither spotted the police vehicle, but when they did, JUST as they were passing me (and the other traffic behind me in lane 2) they decided to bang on the brakes AND come into my lane, reducing speed dramatically...(he'd even "tinted" over the rear light clusters, such that the brake lights were "glow-worm" bright... !!)
No options, my brakes had to go on hard to prevent either rear-ending the Audi, or getting VERY close.
On standard brakes/pads and without locking-up, a collision WAS avoided, though no doubt my blood pressure went through the roof and the air in the car was VERY blue !
Upon getting home, and after the adrenaline had finished coursing through my system (thanks to Messrs Gordon and Schweppes excellent products!), I had a wee think.
My slightly elderly BMW 328i has EXCELLENT brakes, with ABS, which gives me a feeling of confidence that in MOST situations, the car will stop safely, in a controlled manner. (You could probably dig it's front panel into the road if you really "stood on 'em".) Bear in mind it has discs all round, vented on the front.
Whilst the Stag's brakes are good enough to (very recently) pass an MoT, and stop the car in most cases, the above incident really set me thinking. I've only had the car 1 year, in which it has done 1600 miles.
I intend to continue using the car as often as possible throughout the year So, are standard brakes good enough for today's driving conditions ? In most cases, probably yes, but...….
We all love our cars, and I have no wish to see it damaged, or have an RTC which MIGHT be avoided if the car stopped a little bit quicker.
So, I have decided to go along a similar route to many Stag owners:- Wilwood plain vented discs with their 4 pot calipers and pads. Expensive, but I can live on beans for a month or two...….
No doubt there will be those who will poo-poo losing the originality of the car, which I can sympathise with, but the trade-off of having better stopping power, and the CONFIDENCE of knowing that it is available, does outweigh originality, and puts the braking system on a par with the modern vehicles that we share the road system with.
And finally....ABS ? Yes, that would be really good to have, but what are the practicalities, and how MUCH cost would be involved...."this isn't gonna be cheap"...…
Safe driving!
Neil.
