Thruster87 Posted April 23, 2007 Share Posted April 23, 2007 Looking at putting better brakes [ has drum brakes ] on the TST. Considering you only need them for holding the plane from rolling on a windy day on tarmac and a bit of [differential brakes] steering? To keep the weight to a minimum what would be an option? Looked at the new push bike hydraulic disc brakes and also the pocket rocket small motorbike hydraulic disc type which fit the budget.Any ideas out there?

Guest TOSGcentral Posted April 23, 2007 Share Posted April 23, 2007 As you say - brakes are not normally needed on a Thruster except for bitumen or holding it for engine run ups and mag drops. You already have drum brakes and these are probably the Drifter type which work well for this application.. Going to a hydraulic system is added weight and complexity for very little (if any) gain. I also hear that hydraulic braking systen can give problems and can be a bit indifferent! If you have to have differential brakes then the way to do it is go a full dual system with two motor bike style levers on the front of the stick, each driving the brake on each wheel. They have to be spread far enough apart for independent operation but close enough together for a unilateral grasp for even wheel braking. But again - if you have a correctly rigged tailwheel geometry you should not be short of adequate steering power so again brakes are something you probably never use unless in unusual circumstances.

Guest jeremy Posted May 28, 2007 Share Posted May 28, 2007 I have replaced my drum brakes with disc brakes they come in a kit from Aviation Belts I had to get the axle threaded (one left and one right) and make a backing plate, the whole system weighs no more than the original and works extremely well, jeremy Link to comment Share on other sites More sharing options...
Thruster87 Posted May 30, 2007 Author Share Posted May 30, 2007 Hi Jeremy, Could you post a couple of pics of your brake setup cheers Link to comment Share on other sites More sharing options...
Guest jeremy Posted May 30, 2007 Share Posted May 30, 2007 sorry i dont own a digital camera but the bloke at aviation belts can email the instructions to you if you contact him his add is in the back of the raAus mag. Hope this helps If not ring me 0880919491/0427803291 Link to comment Share on other sites More sharing options...
Thruster87 Posted May 31, 2007 Author Share Posted May 31, 2007 I was just interested in your setup as I've just completed putting a differential hydraulic disc brake system on mine [used Hayes HD push bike brakes and made my own rotors etc out of 2mm 4130] the only thing left is for the trials/testing to begin Cheers Link to comment Share on other sites More sharing options...
Thruster87 Posted July 3, 2007 Author Share Posted July 3, 2007 Tested brakes today and they worked very well.Held on full power and will slow the aircraft nicely without danger of nose diving it and turns are just brilliant.Hopefully they will be durable.

asmart Posted September 1, 2007 Share Posted September 1, 2007 Hi I was wondering how the braking system was holding up?I recently purchased a set of drum brakes but as yet haven't set them up. I am a bit concerned about the extra weight and they require a bit longer axle bolt which I am concerned may stress the whole axle plus I haven't heard many good reports about them. I would be interested to see your set up so if you could post some photos it would be great.Esspecially of how you mounted the caliphers and disc.

Thruster87 Posted September 1, 2007 Author Share Posted September 1, 2007 This is the pic of the setup and so far so good but only done a few hours to date Cheers Should mention I've changed to a 5/8th axle[High tensile bolts].To do this you need drill/grind the leaf spring very slowly or with coolant.
