on my es2 engined 19s framed mongrel i am just placing the parts back on it to see what fits most of which is none standard. i notice when i place my flipper on the footrest it is always in contact with the brake lever no matter how i adjust the lever or foot rest. i have seen others with longer levers and longer foot rest support arms which would mount the foot rest further back that would probably solve it but i don't know what i have now brake pedal / foot rest wise. its not a problem i will sort it out at some stage just wondered what ya think.

thank you

The first thing I noticed about the pic, Barry, is the crazy angle of the brake operating lever on the hub. You must have inordinately thick brake pads! If you could get that lever to make almost a right angle with the operating rod your brake pedal would drop to a more acceptable level. Or have I missed something? George

BTW the footrest arm looks the same as mine, which is fine, so I don't think that is the culprit. G

its not adjusted up George. all you see in the photo is just been loosely put on to see what is missing just to give an overall picture of whats going on. i am concentrating more so on the brake foot pedal side of things at the moment. at least i know the foot rest arm is ok

thanks Barry

George is on the money, check the hub lever is on the right position, maybe even the internal brake cam is 180 degrees out.

Hi Robert. its an upwards type lever i bought a while ago the original was worn so ive fitted this one with its return spring when its adjusted up it will be more vertical than shown in the photo.

thanks

Just above the pivot is a bolt with a locknut on the pedal. This should locate on an abutment on the frame lug to act as an adjustable stop. The bolt may be too short (maybe broken off) or the abutment may have sheared off.

Ian is on the right track, the pedal sits far too high. The adjustable stop should be used to bring it slightly below the footrest level. The brake arm should be set so the maximum leverage is applied when the brake is applied i.e. 90 degrees to the pull wehen active. You will notice the wear pattern on the knurled surface of the pedal where you slip your toe on and off....

Otherwise it looks very tidy bike.

Ian .

the adjuster is in mid air nothing to adjust against so i can only assume something has departed from the lug on the frame .

Jonathan.

with the aid of the adjuster i can get it correct or at least somewhere near. with nothing to adjust against the only thing i can think of doing is makeing a bracket that goes between the back of the foot rest and the lever pivot and incorperate a small flat elongated plate on the top for the aduster to sit on. or weld one to the foot rest shaft .will have a think about it.

thanks Barry

I think that the brake pedal is for a rigid or plunger model. The adjuster would work for that.

The brake arm should probably be a downwards type, the upward type was for late featherbed twins for exhaust clearance.

The brake operating lever on the hub sites "downwards" on my bike. Don't know whether that would make a difference.. Never seen it fitted pointing up. George

As George says, the brake arm should hang down, but that won't help the pedal position. Here's a picture of what the pedal stop should look like which is what sets the pedal position.

I wonder if you have a brake pedal from an earlier bike? The adjustable stop on my 1952 ES2 (plunger frame) looks much like yours and abuts onto the lower frame rail.

I would agree with Ian Soady & Paul, the pedal looks very like the one on my '37 rigid frame. As with Ian's plunger frame the adjustable stop bears against the lower frame rail (which of course is missing on the swing arm frame). Could probably fabricate an alternative abutment but might be easier to acquire the later pedal shown in Ian Goodhall's pic. Upward pointing brake arm on the rigid frame as well.

Paul . as you say it looks like its from another model but i quite like it i think i will make something up to accommodate the adjuster. i know what you mean about the brake arm fitting

George . i have another downward facing brake drum lever knocking about i will change it over

Ian Goodhall. thanks for the photo see what you mean that makes sense

Ian Soady. like you say ian its probably off an earlier bike . i don't think it looks to bad, fit wise

Ian Macdougall. yes it seems it from another model but as i say i quite like the lever its a hefty sort so i think i will make something bolt on to be able to use the adjuster.

thank you all

theres nothing on the tele. so i thought i would have a go at making a bracket so as the adjuster on the brake pedal can function. it still wants finnishing off and a spacer wants adding instead of the nut on the foot rest. but it will do for me.
