Shrewsbury Brake Fitting - New Disc Brakes & Pads

The enforced contact between the brake pads and brake drum or brake disc increases friction to slow down or stop the vehicle

Proton brakes can last for thousand of miles depending on use and regular service

The brake pedal controls the Master Cylinder (a fluid filled hydraulic piston) that transfers stopping power to the brakes

Braking increases hydraulic brake fluid pressure

The hydraulic brake fluid is a non-compressible liquid so braking pressure is transferred via the brake pipes to the wheels and operates a slave cylinder piston that forces the brake pads against a brake drum or brake disc

Modern Proton braking systems use hydraulic links to transfer stopping power

Shrewsbury Proton Brake Repairs

Hydraulic braking pressure forces a brake calliper to press the brake pads against the disc to apply the necessary stopping force

Drum Brakes are an older system than Proton disc brakes and use two half moon shaped brake shoes that move outwards during use to apply a frictional stopping force against the inside of a brake drum

Proton disc brakes have a pair of high friction brake pads mounted either side of a brake disc

Drum Brakes, if fitted, are usually found on Proton rear wheels

In hydraulic braking systems, braking pressure operates a slave cylinder

Proton Brake Servicing - Proton Brake Discs and Pads

The brake pads on your Proton should wear first

Proton brake discs will wear and need replacing eventually and should be inspected for pitting

If the Proton brake discs warp then they should be replaced immediately

Proton Brakes will safely function correctly without the need for replacement for many thousands of miles

if the Proton brakes overheat and are allowed to cool with pressure still applied for m the brake pads/shoes then it is possible for the disc to warp.

Proton Brake Inspection Elements

And carry out the following maintenance of your Proton braking system:-

Hand brake linkage condition

ABS warning light operation

Brake drum condition

General brake disc condition

Correct brake pad movement and level of wear

Clean and remove brake dust and loose corrosion and dirt from drums

Handbrake function and travel

Auxiliary handbrake shoes where appropriate

Wheel cylinder condition

Adjust handbrake

Brake pipe Condition

Top Up Brake and Clutch Fluid Levels or

Lubricate Hand Brake Linkages

Hydraulic brake pipe fittings and joints for corrosion and leaking

Brake calliper operation

Replace Brake Fluid if necessary

Proton Steering System

The tyres will need to be replaced much sooner than necessary until the steering rack is adjusted to bring your wheels into correct alignment

Common symptoms of Proton steering alignment problems include:-
Vehicle Drift - Your Proton tends to pull left or right when travelling in a straight line
Modern Power steering and Drive by Wire Systems do not have the same mechanical linkages between the steering column and drive wheels making it difficult to 'feel' how the steering is performing.

One of the first signs of a potential problem with your Proton steering system is uneven tyre wear

The tyre tread is rapidly removed from the inner or outer tyre edge of your front tyres

Your Proton steering inspection can include:-

Steering Rack Gaiter condition

Correct wheel nut torque to manufacturer's recommendations

Tyre Condition - inc Spare

Proton Tyre wear and wheel alignment

Correct wheel balance, including spare

Steering Linkages for wear and corrosion

Steering Condition

Correct Tyre Pressure - inc Spare

Wheel Bearings for wear - play or noise

Power Steering Reservoir Levels and Top Up

Proton Brake Servicing: Brake Discs, Pads & Hydraulics

Modern braking systems use hydraulic links to transfer stopping power.

The brake pedal is attached the Master Cylinder; a fluid filled hydraulic piston.

The hydraulic brake fluid is a non-compressible liquid so braking pressure is transferred via the brake pipes to the wheels and operates a slave cylinder piston that forces the brake pads against a brake drum or brake disc.

Braking increases hydraulic brake fluid pressure.

Brakes can last for thousand of miles depending on use and regular service.

The enforced contact between the brake pads and brake drum or brake disc increases friction to slow down or stop the vehicle.

Proton Replacement Timing Belt or Cambelt Shrewsbury

Generally Proton belts should be replaced every 60,000 miles or less. So, if you have just bought a secondhand Proton that has 40,000 to 80,000 miles then it is important to know if the timing belt has been replaced or needs replacing. Check the Proton Owner's manual for your model for the recommended changing frequency

The toothed belt connecting the engine crankshaft to the camshaft is known as the Cambelt or Timing belt

If the timing belt snaps it will most probably cause serious engine damage. The camshaft stops turning with some of the valves left in the open position. In a Free Running Engine there is enough clearance between a fully open valve and the piston head to avoid serious damage. In an Interference Engine there is no clearance and the engine relies upon accurate timing to keep the valves and piston head separated. With a broken timing belt; the inertia helps the crankshaft to rotate freely forcing the pistons to strike the open valves resulting in damaged valves, pistons, and possibly even damage to the cylinder head

Often it is prudent to replace a combination of items associated with the timing system. Most of the needed Proton parts can be obtained as timing kits containing the appropriate timing components; such as: Proton timing belt
timing belt tensioners
timing belt tensioner idler roller
front lower crank shaft seal
water pump gasket

Since Proton Timing Belts are hidden inside the engine they tend to be forgotten when purchasing a used Proton

High compression diesel engines are normally interference engines

The Timing Belt synchronizes the camshaft to the crankshaft position ensuring the valves open and close at the correct time in relation to the piston. Some vehicles use a cam chain in place of the belt or a timing gear system instead

Timing belts must be replaced at a specified manufacturer's interval. The timing belt should also be inspected regularly and replaced immediately if there is any evidence of cracking or fraying cuts or excessive wear

Shrewsbury Replacement Proton Clutch

The centre of the clutch disc has a spline pattern that matches splines on the power input shaft of the transmission system

Engaging the clutch forces the clutch against the flywheel transmitting power from the crankshaft to the transmission shaft

When the clutch is dis-engaged the clamping force is removed so the clutch disc spins with the flywheel and no power is transmitted

Disengaging the clutch acts on heavy-duty release springs to isolate the pressure plate so that the disc is no longer pressed against the flywheel

The pressure plate comprises heavy-duty release springs, a metal pressure ring acting as a high friction surface to interact with the clutch disc, a thrust ring (or thrust fingers) for the release bearing, and release levers

Proton Clutch failure often occurs when one or more of the high friction surface materials wears out on the disc. Even when the pressure plate is engaged and a clamping force is applied, there is no longer sufficient friction to transmit power without the clutch slipping. Normally the Proton clutch disc and pressure plate are replaced. Replacing the Proton Clutch is a major operation and it is sometimes advisable to replace a number of items, often supplied as a Proton Clutch kit:-
Proton clutch disc
pressure plate
release bearing
pilot bearing - bushing (when required)
internal Proton clutch slave cylinder

The Proton clutch disc is, not surprisingly, a disc with each side covered in a high friction material. It is designed to engage with the high-friction surfaces of the pressure plate and flywheel. It is also designed to transmit power to theProton transmission system

Proton Engine Efficiency - Fuel Injection

Proton Re-Mapping Shrewsbury
The Proton ECU can be replaced with a programmable ECU or re-mapped to electronically alter the engine performance characteristics

Proton Fuel Injection
Fuel injection systems mix fuel with just the right amount of air for optimal combustion & energy release in an internal combustion engine

Proton Engine Mapping
The Proton ECU controlling engine performance is pre-programmed with software containing embedded data on engine performance for different combinations of engine speed and acceleration

EFI - Electronic Fuel Injection
The Proton fuel injection system is controlled by a mini-computer or Electronic Control Unit (ECU) that assimilates data from a series of temperature sensors and oxygen or lambda sensors providing feedback to help optimise fuel efficiency and power under a variety of conditions

LPG Petrol or Diesel Metering
Fuel Injection systems have replaced carburetors for the accurate mixing and delivering of petrol, lpg or diesel fuel in modern Proton vehicles

Proton Maintenance - Oil & Filter Change Shrewsbury

Oil Composition
Engine Lubricating Oil is composed of hundreds of chemicals; some can interact chemically, polymerise, oxidise and break down with the extreme conditions of temperature & shear forces pulling the oil molecules apart in your Proton engine thus, changing the lubrication properties.

Oil & Filter Change
A new Proton oil filter and oil change shouldn't need a specialist Proton engineer and is minimal compared to the cost of an Engine Rebuild; with regular maintenance and routine servicing working out cheaper than disaster recover when your Proton engine fails

Synthetic Oil Change - Shrewsbury
Modern synthetic oils can last longer than old petroleum based multigrades because they are more inert with a laboratory designed molecular structure and fewer natural catalytic impurities that increase oil breakdown compared to the cheaper engine oils

Oil Change Masterclass
Keep a small amount of the engine oil used in your next oil change in a sealed container; then when you check your oil level with the dipstick you can compare the lubricity or lubricating properties of the oil against your fresh oil:- If the oil on the dipstick seems thin compared to your reference oil sample; it may be time to get an oil change to keep your Proton running smoothly

Moisture Scavengers - Detergents - Acidity Regulators
Moisture scavengers, detergents and acidity regulators prevent all kinds of contaminants degrading and abrading the internal moving surfaces of your Proton engine minimising the effects that water, particles, and fuel combustion residus can have on Proton performance
Once they have absorbed the maximum amount of water and other contaminants; the risk of corrosion and failure in your in your Proton engine increases

Anti Oxidants
Preventing internal engine oxidation in your Proton motor is the job of sacrificial anti-oxidants present in the lubricating oil; Anti oxidants are sacrificed to protect your engine and will eventually be depleted making it necessary to change your oil regularly

Oil Change Frequency
The mechanics rule of thumb with traditional multigrade engine oils used to be "change the oil every 3000 miles" but many vehicle manufacturers indicate 5000 to 7000 miles. Initially, follow the Proton recommended oil change guidelines to ensure you validate your warranty.

Proton Exhaust Fitting Shrewsbury

The Proton exhaust system allows poisonous gases from the fuel combustionto vent into the atmoshpere away from the driver and cabin

Explosions from the instantaneous ignition of the compressed fuel and air igniting in the combustion chamber creat a lot of noise that needs to be silenced in the urban environment

Corroded exhaust pipes allow fumes and noise to escape; increasing the risk of poisonous carbon monoxide entering the cabin and significantly increasing noise making detection an easy task

The exhaust pipework helps muffle and deaden the noise from the fuel combustion process
