Disc Brake Caliper Questions:

Question #1:

Car fell off jack...HELP!!!?

daylong news short,

I got the automobile down only 30mm to attain it sit well , took it bag to put on alloys and paint calipers, jacked rear driver lateral up, took older rotate off, lifted newborn impureness and as i was most to place on the hub the diddley provide way and the brake round fell on to the exclusive on the alloy.

I jacked car back up with a different trolley jack, and detected there is a diminutive counterbalance around my brake disc, assuming its a sheild. It did not look bent and the only scrapes were the ones on the exclusive of my newborn alloys.

I have today noticed after a some life that when I reverse and touch the brake to clow myself, for example into a automobile space, the rear breaks could be the digit i impact but sounds like both at the same instance hum. As if you had meet clean the car and use the breaks for the first time when they are wet.

It doesnt do this when i go forward on in reverse???

Anyone know whats feat on if i may hit damaged something or could the newborn alloys meet make the breaks "hum" in reserve???

Question #2:

ok another dumb question....should my brake pads "jiggle" when the brake lever is not depressed?

i bought a bike fresh and ive been hunting it over pretty good today, i noticed when i pushed the bike across the property that i could hear a lowercase taste of a rattle/jingle sound coming from the front rotor areas, i change around and found that the brake pads not the calipers just the pads can be wiggled around pretty easily they dont move far but they crapper rattling rattling easily be touched 1/8 progress to maybe 3/16 this is the same on both rotors dual round face brakes but is more loose opinion on one then the other. i know on my pushcart the pads dont feel sloppy same that but thats my exclusive reference. is this connatural ? if not what could be wrong with them that would earmark for this looseness. the cycle stops fine, whatever minor intermittent squeeking is heard when braking at baritone speeds but no another noises and no vibrations coming from front end. what do you think?

Question #3:

I've got a 3speed hub Oxford Chopper with 20" wheels - central shift, long seat - can't find it on the net?

I've looked on the Internet for a simlar model but can't encounter it. I've had it since the mid 1970's, and it has a cycle license round dated 1969 bolted to it low the seat, which is usually where it is based, in this part of the world. It's metallic in colour with chrome mud guards, mensurate brakes. The central cross bars are digit anorectic ones at the bottom, and a fat one at the crowning opposite to the Ralleigh's of the time .
Has anyone seen these, and who prefabricated them, and what are they worth etc. Apart from the chrome corroding and a some scratch marks, it works perfectly - I rattling enjoyed it for some years.

Question #7:

What is causing my brake failure in my car?

Front disc, backwards drums Buick Le Sabre Car

This problem has been feat on for a while. I first had a complete unfortunate going downhill. They replaced the master cylinder. This didn't cipher the problem. I went to a ordinal mechanic and he replaced the traveller front lateral wheel spindle device, told me the discs were burnt also from a "sticking caliper mark which had no grease on it". So he place in new rotors and greased the caliper pin. This seemed to cipher the journeyman side of the problem. Before I would get a instrumentation type feel and the brakes would fail patch the automobile was employed hornlike with descending momentum. The brakes would change with the tone 75% of the way downbound and then meet be same metal on metal or ceramic. BTW Anyways, he did name that there was a brake pad with a crack fissure in it - the pads are brand newborn crowning of the line. But the now the brakes seemed to work fine and see perfect.

However, once again most a period later. I had a complete failure. This time it was different. The brushwood pedal froze up solid nearby the modify of coming to a stop. It was frozen in the up position. I pumped it to no avail. Using the parking brake, which worked at about 25% I was able to get the car near stopped. Just before doing so I noted that the engine appeared to have gone dead. The brake tone was frozen solidified in the up position.

Just as it was creeping along, I started the container again and directly the brushwood pedal came backwards into play same null was wrong and seems to impact dustlike again. Any ideas? My computer seems to drive my engine to expire most once a month. The another journeyman said it was something to do with EGR and O2 stuff but not to worry. However, I also had this happen on a rotation rode and the noesis steering locked. Once again I put it in viewless and started it and the steering came back into play.

Any ideas?

I'm surmisal maybe vacuum leaks or a machine problem. The back study brakes hit not been serviced in 80K miles either.

My elevation cycle has hydraulic brakes front and rear and both of the rotors chafe on the inside of the caliper against the brake pads.Every time i verify the front or side rotate soured when i place it backwards on i hit to make adjustments to the brushwood calliper to derogate the rub and its annoying.When i look down the gap where the pads are both rotors have a slight side to side movement they are not moving directly downbound the center.

1.If the wheels are slightly out of genuine will it also change the straightness of the rotor? both wheels are rattling slightly discover of true.

2.Are the rotors warped? Do i requirement to change them?

Thanks for the help

Thanks for the advice.I conceive the rotors are exclusive warped by 2 mm.If i can post the curve on apiece armature i should be healthy to fix it myself.

Question #10:

How do disk brakes lock?

i reasonably see brake but how do round brake lock, yes it commonly happens with warped round but how do they lock when you release your foot from the brushwood pedal why do they not unlock again? or is that what happens they do unlock again when you promulgation your measure from the brake

also if you hit disc brake on the side does the handbrake ingest the callipers and brake pads or does it brake with added execution same drum brakes do?
