| | Posted : 04 Jan 2019 - 08:40 Post title : Front brake upgrade. | | | I have always though that the brakes on the Tbird where adequate, not impressing, but adequate. That was when I still was running 19" at the front, but with my new wheels, 21" at the front, I started to feel that the brakes become inadequate. 2 finger braking has become more difficult, and I mostly use all 5 fingers.
Further considering a power upgrade, I thought it might be wise to start with upgrading the brakes.
Condition : Any solution must be able to work with the OEM Master Cylinder ( MC ).
First thought was to fit 340mm rotors, instead of the OEM 310mm. This proved to be insufficient.
Second thought was to source and fit bigger calipers, with more pot area, but my research showed that most calipers have approx. same total area, regardless if 4 or 6 pot calipers, so no advantage there. There are a few racing calipers out there with bigger pots, but there cost more than the nose of a jet fighter, so not realistic. Furthermore both of the solutions would require a special adapter bracket for the calipers, which clearly would show that it was an aftermarket fitment. I like it clean and OEM like, so not my first choice.
Third thought, a custom designed caliper, tailor made for the Tbird, increasing brake torque significantly.
Here are the numbers of increased torque for the 3 above solutions with the same force applied to the MC. :
1 11%
2 5-25%
3 25-40%
Or in other words, reduces force at the fingers, then just with a - in front ( eg -11% etc. ).

| | Posted : 04 Jan 2019 - 14:12 Post title : Re: Front brake upgrade. (Re: bnz433) | | | When the T-Bird was my only bike, I thought that the front brake was "a little weak" too. I now put more than double the miles on my Tiger 955i than I do the T-Bird in a given year and have come to realize that the T-Bird's front brake is not "a little weak", but really inadequate. I've tried several different pads; sintered, organic, ceramic, all with similar results.
I also found out when converting my America to the Speedmaster's (dual) front brake, that any increase in caliper piston area requires an increase in MC piston area as well. After all, if you're pushing more fluid to a larger area, you'll need a bigger pusher! Now add in ABS into the mix....
I really hope that your research finds a solution at a reasonable price. The T-Bird has few shortcomings, but I feel that this is the biggest one!

You certainly did dig out some old post.
The matters mentioned will be discussed further down this post, as the discussion progresses.

You certainly got that right. It's a vital part of the equation, and so it is in my calculations.
When I asked Fab for a elaboration, it was because he used the word "better" and not "bigger" MC. So I was curious what he meant by that.

| | Posted : 04 Jan 2019 - 18:14 Post title : Re: Front brake upgrade. (Re: Slcharger) | | | Anyway, referring to the previous mentioned 3 options, I decided that the best solution would be a plug and play solutions, direct replaceable caliper to the Nissin ones, but with larger pot area and larger pads, still working with the OEM MC.
Making it as easy as possible ( and cheap ) I decided to reuse the pods from the Nissin's, and add some further easy accessible pods to make them 6 pod calipers. The OEM pods are 34 and 30 mm. pods, so by adding a further 27 mm. pod the pod area would be increased by 35%, and so would the breaking power.
I found that the easiest way to get hold of the 27 mm. pods, was to buy a used caliper on Ebay, from a Hayabussa, where there are 4 of these in one caliper.
To get brake pads large enough to run with this setup, I choose pads from a Buell bike, also because they are fixed with 2 pins, allowing for a center support of the caliper half's.
Calculations show that adding those 4 x 27 mm. pod's will increase the movement of the brake lever from 19 to 26 mm. and that to achieve same brake force, with 2 fingers, is reduced by 43 N ( 4 kg ) pulling force.
The increased movement of the lever is depending on how much the caliper is flexing under load, and how much the hoses are expanding during pressure. Reducing those values will decrease the lever movement and give a more linear brake feel. So will the the larger pads, as the load pr. cm2 is less.
Enough for today, I will explain more detailed in a further post, when I am closer to a finished design.

I know exactly what you mean, and that*s why I have spend a considered amount of time optimizing for stiffness. I will show you the result in a short time.

| | Posted : 10 Jan 2019 - 03:56 Post title : Re: Front brake upgrade. (Re: Slcharger) | | | Maximum brake load calculation , 450 kg total weight, 80% weight transfer to the front wheel, road to rubber friction 0.9, my new calipers fitted, pads with friction 0.35, the braking torque would be approx. 950Nm. This would be achieved with a pull on the brake lever, with 120N equal to ( approx. 12kg ) or 26 lbs. force. This again is equal to a pressure in the hydraulic system of about 15 bar, or 218 Psi.
Applying this pressure to the caliper chambers, forcing the pot's to force the brake pads to the rotor, result in a maximum deflection of the caliper of less than 0.1 mm. or 0.00043 inch.
I use FEA ( a stress and displacement calculating software ) to exactly calculate what is happening. So to optimize the design, you start with a design you think will work, make some calculations by hand, optimize, and calculate by hand again. Then you use the software for refinement, and about 25 iterations later, you have got the result you wanted, in this case, a very stiff caliper with very little flexing.
This picture show the deflection of the caliper, when the bike is standing still. The dark colors mean lowest deflection, and the red color means highest deflection. The scale is at the left. Please note that the reason both parts don't deflect equally, is because stiffness is transferred to the outer part, from the connection points.
This picture show the deflection, when the bike is in motion. The difference comes from the force the pads apply to the caliper, in rotational direction, and the bending moment applied to the connection points. Due to the eccentricity of the connection point, in relation to the rotor, the caliper try to bend away, but in reality it is only 0.02 mm. so no concern.
When you do design where stiffness is criteria, then stress loads are normally not an issue. In the picture below you see the stress applied to the caliper for both situations described as above. The stress is way below any critical value, even the hot spots ( red color's ) are of no concern. The red areas where the bolts are fitted are caused by the pre tension of the bolts. In fact the caliper can withstand a hydraulic pressure from a panic braking / lock up wheel, with a force applied to the brake lever of 700 N or ( approx. 70 kg ), or 154 Lbs. force.
These pictures are just to show you that this design is not a coincidence, just looking smart ( at least I believe so ), but a result of iterative design. All loads, torques and forces have been taken into account, and appropriate safety factors have been applied to both material stress and loads.
I hope that this design will lead to a better brake feel, more linear, and a true 2 finger braking.
Trail test will show, now I need to get the parts machined.

Thanks Peter.
It is not my best work, to date, but it will do.
It is partly what I am doing on a daily basis, as an Engineer, although my work has become more administrative since I years ago was promoted Senior Project Manager. But as they say, once you learn to ride a bike, you never forget.

So do I Lee.
We are in the middle of winter here, so there will be a few month until weather allow for a test ride.
But first things first, the installation, and first impression.

DM they are designed to replace the Nissin's and will work with OEM rotors.
In regard to manufacture and sell the calipers I would be happy to help the community, if there is enough interest. I don't want to make any profit on it, just cover my cost. Numbers are though of essence, as initial cost, like setup and and take down hours on the CNC machine cost the same regardless if they machine 1 or 20 calipers. When I have machined the first set, I will know a lot more about the cost.

(Re: DangerMouse) | | | I hated the brakes on my bird when I first got it, as being used to sports bikes was really only using the front, and the big girl was struggling to pull up. Ive just changed the front pads to a set of Sixity Organic pads and they bite real nice, nice feel and gave them a workout today and they hold up fine. Ive run the in a 955 Daytona and a Sprint 1050 as well and find them pretty good pads
