![]() ![]() Although pads are relatively cheap, for a child's bike I recommend a good brand like Koolstop as children do not have the arm strength needed if the brakes are not working well. When you have got as much as you can, drip a light oil over the inner and slide the outer up and down a few times and wipe clean.Īlso consider putting on new brake pads – the pads harden with time and lose effectiveness meaning the braking is not as good as it should be. Unhook the cables so the outer can slide up and down the inner easily, using a clean rag, wipe the inner clean and slide the outer up and down. You do need proper cutters to do the job easily though – so it could be worth getting your local bike shop to do it.Īlthough the best option is to replace the cables (Inners and outers), you may get away with a clean and lube. Cables are considered a consumable item, and replacing them is not expensive or particularly hard. In your case, I suspect the problem is too much friction in the cables. In that case even a line lock will work.Īll this is out the window though if your local DMV requires a separate mechanical brake system on their vehicle inspections.Have a look at Park Tools website for advice on how to adjust the brakes So if it's just a parking brake your concerned about then all you need is something that keeps the car from rolling when parked. Maybe that's why manufactures always refer to it as a parking brake to avoid liability. Have you ever tried to stop a mid size car at 70 mph with the hand brake? Not exactly an emergency stop. The diagonal split allows better braking if just one circuits working than a front to rear split if just the rears are working.Īnother thing to consider is how much effective braking force is obtainable with a mechanical hand pull system. This doesn't work though if you want to adjust front rear bias, so the system needs to be split front and rear on separate circuits in that case. Usually the system is split diagonally with the left front right rear and right front left rear on separate circuits. But modern systems have two separate hydraulic circuits so there is already built in redundancy. Is it an emergency brake or a parking brake? If it's an emergency brake then it's a back up to the regular hydraulic system in case that fails. You can spot a bike with disc brakes from 100 yards away the large. ![]() disc) which is mounted at the hub of the wheel, while in rim brakes, the braking force is applied directly to the rim of the wheel. In disc brakes, the force is applied at the rotor (i.e. Now you have to consider what a modern emergency/parking brake really is. The main difference between disc and rim brakes is where they apply the braking force. This saves weight and means less parts to break. They did have a parking brake of sorts which was a hand brake handle under the dash that connected to the brake pedal so that you could pull the brake pedal down and lock it in position. Many of the original cars including the MKV that I'm familiar with had no separate emergency/parking brake. The Ultralite 2's are a direct replacement for the Ford Cosworth rear calipers. Allows conversion of current Trojan hydraulic calipers to include a mechanical park brake. Prices are per caliper & Ex the Gordon Brown. Fortunately for me Frank Catt at Wealden Engineering was generous enough to donate a pair of Billet 4's he had going spare. Not a cheap option, as the AP calipers were £300 a pair! Which, plus the cost of the calipers, would have been £770.00 per pair. Unfortunately, HiSpec are 2 years to late with this development for me as I had to use HiSpec Billet 4 calipers on the rear with a seperate AP Handbrake caliper. They have developed their Billet 4, Ultralite 2 & Monster4/6 calipers to include an integral handbrake.Prices are very reasonable & the quality of their calipers is exellent.Indeed, quite a few people I know are using several types & combinations of these calipers on their race cars. HiSpec Motorsport here in the Uk has solved the problem of having to install a seperate handbrake claliper. ![]()
