Merlo brakes??

[Cmoran]

I’ve a 40.7 with no brakes where’s do I start looking? It’s full of fluid and handbrake works. I’ve read somewhere that it could be from lack of use but would like to get them working if not to expensive. TIA

Not a Merlo expert but because like so many Hydrostatic machines you drive it on the accelerator, which means you don't use the brakes hence on a Merlo especially the brake caliper pistons stick, hence when you do use them the pistons stick on generating massive heat so any loose materials catch fire and that is why over the years you will see many Merlos in scrap yards burnt out IMO
Handbrake works on external rear axle disc so not connected with foot brake not working.

They just have brake discs on prop shaft so just calliper with pads , maybe they need bled .

We had the same when we has one.Use to strip them down and give a good clean every six months.It helped but they were never that good in the first instance.The 42.7 we have today has very good brakes.

Foot brakes separate to hand brake.

More than likely pistons in caliper seized, fairly common on old Merlos as brakes don't get used. Take pads out of caliper and work piston, blow out and rough up pad or replace. If no joy the calipers need stripping down and resealing. Easy job for the right man who knows Merlos!

Thanks folks I’ll take of the callipers when I get a chance and try to free them

If it no brake what’s so ever I’d say bleeding them first and make sure callipers actually work .

Ya there’s no pressure on the pedal and it’s full of fluid

Defo need bled , get someone to help you two person job one to press peddle and one to tighten slacken screw , might even need bit of pipe into fluid off screw , did a motor bike other day had to use a syringe to back feed to get to work.

Crack the bleed nipple on front caliper see if it starts running. Gravity should push the fluid through. Then do the rear.
