Did you regrind the plates and are the new shoes the same type? Replacing the shoes only means they have to wear a bit to fit the grooves in the old plates. Give it time. Also rebleed the brake cyclinders and get rid of that contaminated fluid.
Vehicles with new brakes take longer to stop compared to vehicles with worn brakes because new brakes have not yet been broken in and may not provide optimal friction and grip on the brake rotors, resulting in a longer stopping distance.
If you only did the front brakes, the problem may be in the rear brakes.
To improve the braking performance of your fixie bike brakes, you can try adjusting the brake pads to ensure they are making full contact with the wheel rims, replacing worn brake pads with new ones, and checking and adjusting the tension of the brake cables. Additionally, upgrading to higher quality brake components or switching to a different type of brake system, such as dual pivot caliper brakes or disc brakes, may also improve braking performance.
All cars have the brake system designed to make a loud screeching noise when the pads get low. Most people do not do the proper maintenance on their brakes, which is lubing of parts. This maintenance ensures even wear of the pads and or any problems will be noticed. Most braking is done with the front brakes so rear brakes tend to last much longer. Five plus years before having to do the rear brakes is not unusual.
To install cantilever brakes on a bicycle, first remove the old brakes. Then, attach the new cantilever brakes to the brake bosses on the frame. Adjust the brake pads so they are aligned with the rim of the wheel. Connect the brake cable and adjust the tension for proper braking. Test the brakes to ensure they are working correctly.
Were the rotors resurfaced or replaced, or just the pads? Warped rotors are the most common cause of vibration when braking
New fluid will be in system almost immediately but if you need to bleed system brakes will not perform properly until they have been bled.
You can tell if a Lincoln needs a new rotors by the braking fashion of the car. When applying the foot to the brakes, if the pedal tends to vibrate, the rotors could be deteriorating.
You need new brakes
It depends on the vehicle and how hard you'll be braking! Basically drum brakes are quite old fashioned and can 'lock' under hard braking or if they get wet. This can cause the wheel in question to skid! Most new vehicles these days unless they are very cheap (usually motorbikes) come with disk brakes. They won't lock if they get wet or under hard braking. Also disk brakes can have an extra feature called ABS - or Anti-lock Braking System - what this means is that when you press the brake pedal the brakes automatically turn on and off a hundred times a second or so - actually allowing you to steer. Very good. Nearly all cars and many motorbikes come with this feature as standard or an option.
A distracted driver will have a greater reaction time than a non-distracted driver. A distraction to a driver will increase the drivers' reaction time and reduces the ability to respond to an emergency situation. The driver takes longer to react and more time passes between seeing the hazard and starting braking, so the car travels a greater distance before it comes to a stop. Two important factors to take into account for calculating stopping distances are reaction time and breaking distance. Reaction time For average drivers it takes 1.5 seconds to react to an emergency situation. For a distracted driver it may take as long as 3 seconds. A focused driver driving at 60km/hr will travel approximately 25m before they react, and a distracted driver driving at 60km/hr will travel approximately 33m before they react. Braking distance The breaking distance of a car depends on a number of variables. The slope of the roadway; a car will stop more quickly if it is traveling uphill because gravity will help slow the vehicle. The frictional resistance between the road and the tyres of the car is also important. A car with new tyres on a dry road will be less likely to skid and will stop more quickly than one with worn tyres on a wet road. If the slope and frictional resistance are equal, the factor that has most influence on braking distance is the initial speed. Formula used for calculating braking distance: d = V /(2g(f + G)) Where: d is the Braking Distance (m) g is the Acceleration due to gravity (9.8m/s^2) G is the Roadway grade V is the Initial vehicle speed (m/s) f is the Coefficient of friction between the tires and the roadway (u) A more simple formula used to calculate braking distance can be derived from a general equation of physics. Ignoring friction, and the roadway grade v = u - 2ad where: v is the final velocity (m/s) u is the initial velocity (m/s) a is the acceleration (m/s^2) d is the distance traveled during deceleration(m) Since we know that v will be zero when the car has stopped, the equation can be re-written as d = u/2a The total distance it takes for the car to come to a stop can be found by adding the reaction distance to the braking distance.
Tyre surface: If the tyre is new, it will have surface with depressions which will offer more friction compared to old tyre whose surface-depressions are worn out and it is more flat, so it offers less friction. Therefore, new tyre will have less stopping distance, as force of friction is more. Thinking distance is affected neither by friction between tyre and road, nor by friction between brake and tyre. If road has a wet surface, it has less friction so the vehicle will skid farther, and vice versa. The braking force, i.e, friction between tyre and brake is unaffected by road condition or tyre surface. Hence the distance the vehicle travels WHILE retarding due to "braking force", is not same as stopping distance, because even when the wheels are stopped rotating due to braking force, the car will skid a little distance- this total distance is the stopping distance.
