Did mick mean the pushrod ought to be free to move? Sounds like your brake pistons are seizing....

The thing to remember with reliant rear brake wheel cylinders is they have to slide in the backplates.

That bit can seize up even when the pistons move easily

Thumbs up steve rear trike brakes

hi ya mate
just woundering this might seem like a stupid question taking to brother inlaw yesterday and he rides motorbikes he said he hardly uses his rear brake he always uses the front one unless he has to stop quick cus ive been using front and rear together and my brake fine till it gets hot i havent drove a motor bike in years and woundering if all bikers just use front brake and both if they need to stop quick . im wondering if i am expecting to much of rear brakes thanks for the advice about slave cylinder having to move back plate i had a look this morning they looked ok but ive greased them any way thanks steve

Genrally I think 75% of the braking effort will be through the front brake, which varies according to tyres, vehicle type, driving conditions. On my bikes I can often go miles without using the rear brake, to the extent where I used to get pulled up on it every mot as it had worn the rear shoes out and I'd not realised and I've even had them sieze up from lack of use on a daly ride bike. Still worth looking up how to service yours properly if in doubt.

you need to use the rear brakes on a trike as otherwise the rear end has a nasty tendency to try and ovbertake the front end - a little scary!

And that shows my ignorance of trikes, sidecars I have done, quite a bit too, trikes, not yet. I suppose it makes sence, all that mass at the rear, thinking about it, the sidecar was the thing the rear shoes were always worn out on come mot, the solo siezed it's back brake, mostly on the 2 stroke 125 where I could easilyy hold it from rolling back on a hill start with just my foot on the floor and got too lazy to use the brake.

Use the front too much on a trike and all that happens id the front gets pushed along the road. At least it does on a car based trike......

Had that on sidecars, either under heavy braking with crap (for sidecar) tyres or under hard acceleration on full steering lock. Amasing to think that a skinny 3.50 19 sidecar tyre offers more grip than a wider and fairly flat profile bike tyre that actually had more contact patch. It can be very interesting hearing what works and why.

have you checked that the reservoir is breathing and that the master cylinder is moving freely?
